fix: add PostgreSQL startup wait loop before test database setup

- PostgreSQL container takes time to fully initialize after docker compose up
- Previous fix didn't account for container startup time
- Add explicit wait loop (30 second timeout) for PostgreSQL service to be ready
- Only create test database AFTER PostgreSQL itself responds to connections
- Prevents 'database system is starting up' errors
- More robust and handles slower container startup scenarios
