Enhance content management and user interaction features

- Introduced a new content source toggle in the profile and app header to switch between IndeeHub and TopDoc films.
- Updated the content fetching logic to dynamically load content based on the selected source.
- Enhanced the seeding process to include a combined catalog of IndeeHub and TopDoc films, ensuring diverse content availability.
- Improved user interaction by preventing duplicate reactions and ensuring a smoother voting experience across comments and content.
- Added support for Amber login (NIP-55) for Android users, integrating it into the existing authentication flow.
