Fix hardcoded text and add missing i18n translations in file manager

- Add 18 new translation keys for file manager sidebar and context menu operations
- Replace hardcoded Chinese text with t() function calls in FileManagerSidebar.tsx:
  * Toast messages for remove/unpin/clear operations
  * Context menu items for recent files, pinned files, and shortcuts
- Replace hardcoded Chinese text with t() function calls in FileManagerContextMenu.tsx:
  * Pin/unpin file menu items
  * Add to shortcuts menu item
  * Save to system menu items with dynamic count support
- Add bilingual support for all new strings (English and Chinese)
- Improve consistency with existing i18n patterns
