Upgrade database schema to version 2 and remove unused meta_* columns

- Increment `SCHEMA_VERSION` to 2 in `schema.ts`.
- Remove all `meta_*` columns from database tables.
- Add migration logic to handle schema upgrades and clean up unused columns.
- Modify database models and repository methods to exclude `meta_*` fields for stricter typings and improved structure.
- Refactor and optimize query statements across repositories to align with new schema changes.
