The DeriveIden macro converted DeviceCode to device_code (singular),
but the SeaORM entity expects device_codes (plural). Adds a migration
to rename the table so queries match.

Replace raw SQL CREATE TABLE statements with proper SeaORM migration
system. This eliminates verbose SQL logs on startup and provides
proper migration tracking and rollback support.
Changes:
- Add sea-orm-migration dependency and migration crate
- Create initial migration (m20250101_000001) with all 8 tables
- Update storage::init() to only connect to database
- Run migrations automatically in main.rs on startup
- Remove unused detect_backend() function and imports
The migration system properly handles both SQLite and PostgreSQL
backends with appropriate type handling (e.g., BIGSERIAL vs INTEGER
for auto-increment columns).
