fix(#107): trash/recent/favorites list view rendering bugs

Trash view:
- Fix 'Invalid Date': use item.trashed_at (ISO 8601) instead of item.deleted_at * 1000
- Fix literal i18n key 'files.file_types.file': determine type from file extension
  (pdf, image, video, audio, text, document) since trash DTO has no mime_type
- Fix column alignment: remove checkbox from trash header (not applicable),
  add .trash-header CSS class matching the 5-column grid layout

Recent view:
- Fix header/row column misalignment: add empty placeholder div for indicator
  column and .recent-header CSS class matching the 5-column grid
- Fix missing i18n key: use 'recent.accessed' instead of 'files.last_accessed'
- Fix default typeLabel not internationalized: use i18n.t('files.file_types.document')

Favorites view:
- Fix header/row column misalignment: add empty placeholder div for indicator
  column and .favorites-header CSS class matching the 5-column grid
- Fix default typeLabel not internationalized: use i18n.t('files.file_types.document')

Bump SW cache to v11.
