Migrate History screen database calls to SQLDelight (#6933)

* Migrate History screen database call to SQLDelight

- Move all migrations to SQLDelight
- Move all tables to SQLDelight

Co-authored-by: inorichi <3521738+inorichi@users.noreply.github.com>

* Changes from review comments

* Add adapters to database

* Remove logging of database version in App

* Change query name for paging source queries

* Update migrations

* Make SQLite Callback handle migration

- To ensure it updates the database

* Use SQLDelight Schema version for Callback database version
