GuestLog - StayEntry detail view and improvements:

- Added detail view for StayEntries.
- Added button to delete StayEntries.
- Improve queries of StayEntries using a "query config" record.
- Enabled LazyLoading for all database relations. This will make easier to find cases where required relations aren't explicitly loaded.
