fix: add missing permission checks to file routes and map context menu

- Add checkPermission to 6 unprotected file endpoints (star, restore,
  permanent delete, empty trash, link, unlink)
- Gate map right-click place creation with place_edit permission
- Use file_upload permission for collab note file uploads
