Research direction

First, read the Firebase modular upgrade guide at https://firebase.google.com/docs/web/modular upgrade. Then, scan the codebase for all Firebase imports (likely in src/) and update them to the new modular syntax. Pay attention to any deprecated APIs that may need replacement. The issue does not specify exact files, so a global search for 'firebase' in the repository will reveal affected areas. Consider any breaking changes in Firebase v9, such as removal of namespace based imports.
