feat(firebase): Add Firebase SDK and initialize Analytics

This commit integrates the Firebase SDK into the application to enable Firebase services, starting with Google Analytics.

Key changes include:
- Added the `firebase` package as a dependency.
- Included Firebase project configuration variables in the production environment file.
- Created a new `firebase.ts` utility to centralize Firebase app initialization.
- Integrated the `FirebaseAnalytics` component into the root layout to enable analytics tracking across the entire application.
