This commit refines the API references throughout the application to utilize the new `RevoltAPI` structure, enhancing maintainability and clarity. Key changes include:
- Replaced all instances of `REVOLT_FILES`, `REVOLT_BASE`, and other constants with calls to `RevoltAPI` methods for dynamic URL generation.
- Introduced an `ApplicationPlatform` enum to manage platform-specific URLs, allowing for easier switching between Revolt and PepChat.
- Updated various screens and components to reflect the new API structure, ensuring consistent URL handling across the application.
- Enhanced the `ChoosePlatformScreen` to set the selected platform and navigate accordingly.
These changes improve the overall architecture and prepare the codebase for future enhancements.
