- Moved out extension check to ImageService as that seems more relevant.
- Updated models to use static-style references instead of facade to align with common modern usage within the app.
- Updated custom image_extension validation rule to use shared logic in image service.
- Removed old 'exposeTranslations' system to instead use new component
option system.
- Extracted validation rules into their own service provider.
- Cleaned up some formatting/comments in the repos.
