* NEW: Add phpunit test for Workstation class
Add a CRUD test (create/fetch/update/setStatusCommon/delete) for the
Workstation class, which had no test coverage yet.
* FIX pre-commit PHPStan hook errors on commits with no file in scope
phpstan.neon.dist only analyzes htdocs/ and scripts/, but the
pre-commit wrapper passed every staged file straight to phpstan
regardless of path. A commit touching only files outside that scope
(e.g. test/phpunit/) made phpstan exit with "No files found to
analyse", failing the hook for reasons unrelated to the change being
committed. Filter to htdocs/ and scripts/ first, and skip cleanly
when nothing remains.
* NEW: Auto-activate module workstation in WorkstationTest if needed
Activate module workstation in setUpBeforeClass() when it is not
already enabled, so the test does not depend on the environment's
module configuration. Same pattern as
OpensurveysondageTest::setUpBeforeClass().
Note: this activation is real and persists after the test run - it
is not undone by the transaction rollback in tearDownAfterClass().
Activating a module re-runs its SQL install scripts (CREATE/ALTER
TABLE), which causes an implicit commit in MySQL/InnoDB, same as an
admin enabling it from Setup > Modules would do.
