`.dockerignore` excludes `tests`, so the production build context carries
scripts/test-db-bootstrap.ts without the tests/setup/db-global module it
imports. tsconfig includes `**/*.ts`, so the `prebuild` typecheck fails on the
missing module and every deploy since the test suites landed has died there.
CI never saw it because tests/ exists on a runner.
The script is test-only, so it belongs in the tree that is already ignored.
