Fix unit tests across packages - move tests alongside source files and ensure proper mocking

- Fixed unit test failures in database, rerank, data-source, stored-values, and test-utils packages
- Moved unit tests from tests/ folders to be alongside source files (e.g., slack.ts -> slack.test.ts)
- Ensured all unit tests use mocks instead of real dependencies
- Added DATABASE_URL environment variable to test:unit scripts where needed
- Fixed mock implementations and test assertions
- All 52 unit tests now pass successfully
