fix(cypress): apply the licence key when the estate has none

loginAndUpdateValidKey decided whether a key was already working by looking for the nav tree, and looked for it in the body captured before login. A free tier estate renders the tree as well, so on an unlicensed estate the command took the 'already licensed' branch every time and never applied a key. Every upload spec then lost its feature set: onShowUploadModal shows the locked feature dialog instead of the panel, so input#file-upload never renders. The loaded page is read again after login, the licence banner decides whether a key is needed, and an estate with no key is left untouched unless the caller asked for one - the free tier specs are written against that state. Measured on an unlicensed mock estate: excel.cy.ts 24 failing in 14m 1s before, 24 passing in 5m 44s after; csv.cy.ts 1 failing before, 1 passing after.

+* **debug:** keep the debug toggle state across a page refresh ([3ce006d](https://git.datacontroller.io/dc/dc/commit/3ce006d6b469b4ece2bc769f0a32a1792eb1e774))
+* **editor:** raise the row limits and add a cell limit to the EDIT screen ([3de6655](https://git.datacontroller.io/dc/dc/commit/3de6655f26b7e895f60266e9931b46cfc0053975))
+* **mocks:** read the DC_MAX* options from MPE_CONFIG, and mock the DDL export ([edac9a9](https://git.datacontroller.io/dc/dc/commit/edac9a987aad3e4217641eed43f697f61c4bf739))
+* **startup:** call out a missing SASjs tag on the boot screen ([b24eb73](https://git.datacontroller.io/dc/dc/commit/b24eb731ce089acf496bed1e11a5e34208c1bd11))

 The pre-commit hook requires the gitleaks binary provided by the root `@nogoo9/gitleaks` devDependency, so make sure `npm i` has run in the repo root before your first commit.

+The standard [pre-commit](https://pre-commit.com) route is available as well, and does not depend on the lifecycle scripts above: install it once with `pre-commit install` and the secret scan in [`.pre-commit-config.yaml`](./.pre-commit-config.yaml) runs on every commit. The same scan also runs in CI, so a leaked credential fails the build regardless of which local hooks are active.

 After changing mock services, re-run `sasjs cbd -t server-ci` from `sas/mocks/sasjs/`. After changing the frontend, rebuild (`cd client && npm run build`) then re-deploy so the streaming app picks up the new `client/dist/`. If you are using `ng serve` (step 3), only the mock services need re-deploying; the frontend hot-reloads automatically.

+### Demo and staging sites
+
+A push to `release/**` publishes [staging.datacontroller.io](https://staging.datacontroller.io); a release tag (`v*`, created by the release job after its tests pass) publishes [demo.datacontroller.io](https://demo.datacontroller.io) - workflow file `.gitea/workflows/sites.yaml`, using the `DEMO_DATACONTROLLER_IO` Surfer app password (user `allan`). Both are sites on one multi-site Surfer instance; the demo is its default site. The job builds the mocks as a browser-hosted site (SASjs CLI >= 6.1, `streamConfig.mockWeb`), so the services run in a service worker and the drive lives in the visitor's IndexedDB - there is no server. It runs `makedata` on a throwaway SASjs Server first and ships that drive as `sasjsbuild/mock-snapshot.json`; without it the site opens with no data. The mock ships no licence key, so both sites run on the free tier.

+/**
+  @file
+  @brief Generates the SAS statements that create Data Controller derived variables
+  @details Derived (computed) variables are configured in MPE_DERIVED.  Each
+  row defines one variable, which is created in a DATA step view ahead of the
+  filter, so that it can be filtered on in the EDIT screen.
+
+  The engine lives in @sasjs/core as mp_derivedvars - this macro only supplies
+  what is specific to Data Controller: the control table name, the bitemporal
+  filter that picks the current version of a row, and the list of names that
+  belong to the metadata and may not be used as a variable.
+
+  The macro writes the generated statements to a fileref, so that callers can
+  compose them into a view:
+
+      %mpe_derived(libds=&libds,dclib=&mpelib,outref=dercode)
+      data work.vw_derived / view=work.vw_derived;
+        set &libds;
+        %include dercode;
+      run;
+
+  Alternatively, pass outview= and the macro will build the view itself.
+
+  The filter must be applied by the caller, in the step that reads the view:
+
+      data out;
+        set work.vw_derived;
+        where %inc filtref;;
+      run;
+
+  A WHERE statement applies to the data set named on the SET statement, so it
+  cannot reference a variable that is created in the same data step.  Applying
+  it to the view puts the derived variables on the input, which is what makes
+  them filterable.
+
+  Each statement block is of the form:
+
+      attrib REGION length=$21 label='REGION=<expression>' format=$21.;
+      REGION = <expression>;
+
+  Type and length are declared by the administrator, so the result is
+  deterministic.  VAR_LABEL is optional: when it is missing or blank the label
+  is the variable name, an equals sign and the expression, otherwise the
+  configured label is used as given.
+
+  VAR_DEPS lists every input the expression uses - physical columns and
+  derived variables alike.  The statements are generated in dependency order,
+  so a derived variable may build on another one without a sequence number
+  being maintained.  A cycle is rejected.
+
+  Semicolons, macro triggers and comments are rejected, so a row can only ever
+  be an expression.  A derived variable may not reuse the name of a physical
+  column, and may not reference itself: an intra-row calculation would imply a
+  retained value, which depends on the order rows happen to arrive in.

+  @details The EDIT screen is bounded by two limits - rows
+  (DC_MAXOBS_WEBEDIT) and cells, rows x columns (DC_MAXCELLS_WEBEDIT) -
+  whichever is reached first.  A selection over either is SERVED TRUNCATED:
+  the grid gets the first rows that fit, and sasparams carries TRUNCATED=1
+  plus a TRUNC_MSG naming the limit, which the EDIT screen shows as a warning
+  against the table name.
+
+  Test 1 uses MPE_X_TEST (several hundred rows, few columns) so the row
+  limit alone decides the cap.  Test 2 uses the fixture dctest.wideboy (1000
+  rows x 1004 columns, created and registered by testsetup) filtered to 200
+  rows: that is under the row limit but 200 x 1004 = 200,800 cells, over the
+  200,000 cell limit, so the cell limit decides the cap -
+  floor(200000 / 1004) = 199 rows.

+/**
+  @file
+  @brief testing that selectbox (cell dropdown) values respect Row Level Security
+
+  @details A HARDSELECT / SOFTSELECT rule whose RULE_VALUE is a
+  library.member.column reference has its distinct values read straight from
+  that source table by getdata.sas.  If the source table carries Row Level
+  Security rules, the restricted rows must be filtered out of the dropdown too -
+  otherwise values the user is not permitted to see appear in the cell dropdown
+  while the grid itself is correctly filtered.
+
+  This test makes the runner a 'regular' (non admin) user and restricts
+  SOME_BESTNUM in MPE_X_TEST to one value selected from the data (the demo
+  data holds random SOME_BESTNUM values, refreshed by testsetup, so the
+  value cannot be hardcoded).  The demo data must hold more than one
+  distinct SOME_BESTNUM - true of the SAS-seeded estate, but NOT of the
+  SASjs server mock, which seeds the seven 44 rows only (see the
+  'distinct_bestnum' precondition assertion below).
+
+  Runners whose SAS identity group is the admin group cannot be demoted by
+  editing MPE_GROUPS alone - Row Level Security is skipped for them - so the
+  test reports a skip row instead of running the assertions.
+
+  The call passes a filter (PRIMARY_KEY_FIELD < 100) so the whole selection is
+  served - the unfiltered MPE_X_TEST is above the row limit (642 rows against
+  DC_MAXOBS_WEBEDIT:250) and would come back truncated.  The limits test
+  (getdata.test.1.sas) covers that truncation separately.

+  @details Backend validations should abort when:
+    1. an active row's VAR_DEPS names an inactive (active=0) row of the same
+      table - the engine reads only active rows, so the dependency can never
+      resolve at run time
+    2. a row is staged with active=0 while a surviving active row depends on it
+
+  They should NOT abort when:
+    3. a new active row is added to a table that also holds an inactive row -
+      the inactive row is not part of the dependency graph, so it cannot
+      create a cycle or a stale reference
+    4. a delete-marked RLS rule naming a derived variable is submitted - the
+      rule is being removed, so its variables are not validated
+    5. a delete and re-add of the same variable is submitted together - the
+      re-added active row resolves the dependency
+    6. an inactive row is set active again while another active row depends on
+      it - the re-activation is what makes the dependency resolvable
+
+  The staged loads are aborted by the post edit hook inside the child service.
+  An aborted load leaves its MPE_LOADS row IN PROGRESS, so each assertion
+  matches on the unique reason_txt (the submitted message) rather than any load
+  in the time window - the suite runs in parallel sessions.

+  @details Post edit hooks provide additional backend validation for user
+  provided data.  The incoming dataset is named `work.staging_ds` and is

+
+  Available macro variables:
+    @li DC_LIBREF - The DC control library
+    @li LIBREF - The library of the dataset being edited (is assigned)
+    @li DS - The dataset being edited
+
+  This hook normalises the incoming rows and applies the configuration rules
+  at submit time, so a bad derived variable is rejected while the submitter is
+  still watching - rather than breaking the EDIT screen later, when the view
+  is built.
+
+  VAR_DEPS must list every input the expression uses, physical columns
+  and derived variables alike.  The hook checks the part that does not need
+  the target library: a derived variable referenced by an expression must be
+  declared, a variable may not depend on itself, and the resulting graph must
+  be acyclic - across the incoming rows and the current rows they do not
+  replace.
+
+  The target table is not assigned in this context, so the collision between
+  VAR_NM and a physical column, and the resolution of a physical dependency,
+  are left to %mpe_derived, which runs with the target library assigned.
+  Uniqueness on the business key (LIBREF DSN VAR_NM) is checked by mpe_loader
+  before this hook runs, but on the raw submitted values, so it is case
+  sensitive: 'Region' and 'REGION' for the same table both pass the loader and
+  collide only at approve time.  The post-normalisation check below rejects
+  the second one at submit time, naming the variable.
