BREAKING CHANGE: setupTestServer() now returns *TestServerSetup instead of (*httptest.Server, *database.Queries, *config.Config)
This fixes the database connection and goroutine leak issues where:
- Each test created a new pgxpool (default max_conns = 4)
- connManager.StartCleanupTask() goroutine was never stopped
- queueProcessor.Start() goroutine was never stopped
- ~160 tests = potential 640+ leaked connections
New TestServerSetup struct provides:
- Automatic cleanup via t.Cleanup()
- Proper goroutine cancellation
- Database pool closing
- Thread-safe close() method with mutex
Phase 1 of test cleanup refactor.
