makedata writes services/settings.js - the JS twin of the settings program the
backend generates in %mpe_init - with dc_libref, dc_admin_group, dc_staging_area
and dcpath. dcInit() reads it. getdata and viewlibs used it; the other thirteen
services that load dcMockUtils still carried const dcLibref = 'DC_JSLIB' and
built their paths from it, so a deployment with a different DCPATH kept working
in two services and broke in the rest.
Each of those services now loads dcMockUtils first and takes its libref from
dcInit(driveRoot, appLoc).dcLibref, with 'DC_JSLIB' only as the default for a
drive makedata has not seeded. Services that computed paths from the constant
(stagedata's staging directory, getapprovals' data directory, gethistory's) have
the eval above that line, so the derived paths come from the settings too.
Two services do not load dcMockUtils at all - createdemodata and getrawdata
carry their own table and format helpers - so they keep naming the constant, and
say why in a comment: adding the eval just for the settings would collide with
their own helper names.
mock-settings.test.js gains a case that would fail without this: it renames the
control library, moves the data, rewrites the settings file, and asserts a row
written into MPE_SUBMIT comes back from approvers/getapprovals. With the
hardcoded service it is empty, which is the failure mode this removes.
