Live-DB test (TEST_DATABASE_URL-gated) for Phase 3 Slice 5 that
covers the full chain:
1. Migration smoke: post-mig 087, no project points at a
non-fristenrechner-category proceeding_types row.
2. ProjectService.Create with a litigation-category id returns
ErrInvalidProceedingTypeCategory (service-layer guard fires
before any DB write).
3. mig 088 trigger rejects a raw INSERT that bypasses the Go
service — defence-in-depth assertion. Errors on the trigger
raise; test asserts a non-nil error.
4. Fristenrechner-category id (UPC_INF) succeeds. The created
project carries the expected proceeding_type_id.
The four sub-assertions hit each layer of the guard chain (picker
filter → service guard → DB trigger) plus the migration smoke. Any
regression in the chain surfaces here before the deploy.
Tests + main build clean; live test skips when TEST_DATABASE_URL
is unset.
