docs: update README and fix typos across codebase

Enhances README with comprehensive feature categorization including Media Playback, Media Management, and Advanced Features sections

Expands documentation for music library support, search providers (Marlin, Streamystats, Jellysearch), and plugin functionality

Updates FAQ section with more detailed answers about library visibility, downloads, subtitles, TV platform support, and Seerr integration

Corrects typos throughout the application:
- Fixes "liraries" to "libraries" in hide libraries settings
- Changes "centralised" to "centralized" for consistency
- Updates "Jellyseerr" references to "Seerr" throughout codebase

Adds missing translations for player settings including aspect ratio options, alignment controls, and MPV subtitle customization

Improves consistency in capitalization and punctuation across translation strings
