refactor: update icon components to use CSS variables for fill colors

- Changed fill attributes in Upload, Video, VideoPlayIcon, hard-drive, and shield-user icons to use CSS variables for better theming.
- Removed index.ts file from icons directory as it was no longer needed.
- Updated AppButton component to support new icon sizes.
- Modified AdsVastTable to use icon buttons with updated filled icons.
- Replaced inline SVGs with icon components in NotificationSettings, SecurityAccountStatusRow, SecurityChangePasswordRow, SecurityEmailRow, SecurityLanguageRow, SecurityLogoutRow, and SecurityTelegramRow for consistency and maintainability.
- Added new CSS variables for fill colors in uno.config.ts.
