Fix CI healthcheck endpoint and bundled install FK violations

Two bugs preventing the test-runners CI job from passing:

1. Health check used GET /api/v1/auth/login — a POST-only route that
   always returns 404. Changed to GET /api/v1/health which exists.

2. Bundled package install passed empty strings to FK-constrained
   columns (global_settings.updated_by, workflows.created_by),
   causing FOREIGN KEY constraint failures on every surface and
   workflow package. Fixed by resolving the bootstrap admin user ID
   at startup and threading it through the install path.
