[Lukecsharpwalker]

This pull request includes significant changes to migrate the project from Firebase to Supabase, along with various updates to dependencies, code structure, and functionality. The migration involves removing Firebase-specific configurations, services, and functions, and replacing them with Supabase equivalents. Additionally, there are improvements to the AddPostComponent and new features for the admin module.

Migration from Firebase to Supabase:

• Removed Firebase configuration files (.firebaserc, firebase.json, functions/.gitignore, functions/package.json, functions/src/index.ts, functions/tsconfig.json) and Firebase-related dependencies from package.json. [1] [2] [3] [4] [5] [6] [7]
• Added Supabase dependencies (@supabase/supabase-js, supabase) and created a new script reset-password.ts for managing user passwords via Supabase's Admin API. [1] [2]

Updates to AddPostComponent:

• Refactored form initialization to use FormControl directly instead of FormBuilder. Removed Firebase-specific types like Timestamp and replaced them with generic types. [1] [2]
• Updated the AddPostComponent template to resolve a merge conflict and improve functionality.
• Replaced Firebase Firestore-based API calls in AdminApiService with placeholders for future Supabase integration.

Admin module enhancements:

• Introduced a new AdminComponent with a standalone setup and added a router outlet. Included a basic unit test for the component. [1] [2] [3]

Dependency and configuration updates:

• Updated angular.json to include new CommonJS dependencies and modified the prerender configuration. [1] [2]
• Removed @angular/fire and Firebase-related dependencies from package.json. Added new dependencies for Supabase and other utilities. [1] [2]

Miscellaneous improvements:

• Refactored the AppComponent to encapsulate cookie consent logic in a private method.
• Fixed minor import formatting issues across multiple files. [1] [2]

These changes collectively streamline the project's backend functionality, enhance the admin module, and align the codebase with Supabase's ecosystem.
