fix: mark failed uploads in store, surface errors, validate extensions on drop

- uploadFile now catches errors and sets status to 'failed' with error message
- Both create page and drag-drop check uploadFiles results for failures and
  show error notifications
- Drag-drop validates file extensions against bucket allowedFileExtensions
  before uploading, rejecting disallowed files with a notification
