Remove unused tinybeans fields and parsers

The import command only uses Entry.UUID and Entry.MediaPath, so all
other parsed data was dead code. Removed Journal, Follower, and User
types along with ParseJournal and ParseFollowers. Trimmed Entry to UUID
and MediaPath only; Type is now a local variable inside readEntry used
solely to resolve the media filename.

Tests verify only the fields the application actually reads.
