Remove refresh icon and fix Safari/WebKit runtime errors

- Removed manual refresh button from frontend (kept auto-refresh functionality)
- Fixed WebKit 'object cannot be found' error by replacing absolute positioning with flexbox
- Added lazy loading to images to prevent preload warnings
- Cleaned up unused imports and variables:
  - Removed unused useRef import
  - Removed unused colors state variable and colorService
  - Removed unused ColorSwatch import from FilamentTableV2
  - Removed unused getModifierIcon function from MaterialBadge
- Updated tests to match current implementation
- Improved layout stability for better cross-browser compatibility
- Removed temporary migration scripts
