Refactor: Eliminate duplicate types - Use handler types directly

- Deleted templates.CollectionDetailData - using templates.CollectionData everywhere
- Deleted templates.BookData - using handlers.BookInfo everywhere
- Deleted templates.DeviceData - using handlers.DeviceInfo everywhere
- Deleted templates.ProgressItemData - using handlers.ProgressWithMedia everywhere
- Deleted templates.convertDevices() helper - Use handlers types directly in templates
- Enhanced handlers.ProgressWithMedia with device metadata fields
- Added handlers.getDeviceIcon() helper
- Updated all templates to import handlers package
- Cleaned up unused imports

This aligns codebase with templ's design philosophy (use Go types directly, no parallel type system)
