test(security): gate the job-state abort assertions on Viya

The abort cases in getcols, getcolvals.test.4, getrawdata.test.1 and
validatefilter.test.1 assert that the child program was canceled by reading
work.results, the job table %mv_jobflow writes in the Viya branch of
%mx_execute. The SASjs Server and SAS 9 branches call %ms_testservice
instead and produce no such table, so the data step fails with "File
WORK.RESULTS.DATA does not exist.", the flag stays 0 and the assertion
reports (0=1) - a failure that says nothing about whether the service
validated its input.

Each case is now wrapped in %if %mf_getplatform()=SASVIYA, with an explicit
skip row on the other platforms, so the suite reports what it actually
measured.

Verified on SASjs Server (sas.4gl.io, target sas719): the four programs
report PASS with "skipped (the job state it reads is only written on Viya)"
for the gated cases. sasjs lint: 0 errors, no warnings in the four files.

Both are sites on one multi-site Surfer instance; the demo is its default site.

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 estate carries no licence key, so CI runs on the free tier until a key is registered through the licensing screen (`admin/registerkey`) - the Cypress setup does that for the specs that need one. The Sites job writes a licence into the published drive, so demo and staging are fully usable. The pair lives in `sas/mocks/mock-licence.json`: the two values are one RSA key and are regenerated together, and the `.gitleaksignore` entries for it are line-scoped, so inserting a line above the pair re-fires the scanner rather than revealing a new secret.
