GuestDocument Versions - Part 1:

- Changed GuestDocument PK from `DocumentType`+`DocumentNumber` to to `ID`+`Version` for future versioning.
- Added DB field "IsLastVersion" to simplify queries where only last/current version is allowed.
- Updated GuestDocument DB fields type for `CreateTime` & `UpdateTime` to add precision.
- Updated usages of GuestDocument PK to new PK.
- Limit delete of a GuestDocument when it's currently used in a StayEntry.

Note: DB changes require recreating db tables, so all data is lost and migration "rollback" is not allowed.
