Add initial database schema and journal entries for token management

- Created a new snapshot JSON file (0003_snapshot.json) defining the schema for tables including account_tokens, accounts, checkin_logs, events, model_availability, proxy_logs, route_channels, settings, sites, token_model_availability, and token_routes.
- Added columns, indexes, and foreign key constraints for each table to ensure data integrity and relationships.
- Introduced a journal JSON file (_journal.json) to track schema versions and changes, including entries for version 6 with relevant tags and timestamps.
