refactor(database): improve database initialization and backup handling

- Rename init script from init.sh to 00_init.sh for better ordering
- Rewrite database initialization script to support backup restoration
- Add proper migration handling with schema_migrations table
- Fix indentation and quoting issues in docker-compose.yml
- Remove old 00-init-db.sh script as it's replaced by new implementation
