Prompt to reset library data/files on loss of write access

On reset, items are overwritten with pristine versions if available and deleted
otherwise, and then the library is marked for a full sync. Unsynced/changed
files are deleted and marked for download.

Closes #1002

Todo:

- Handle API key access change (#953, in part)
- Handle 403 from data/file upload for existing users (#1041)
