feat: configure WAL mode for improved database performance

- Introduced a new method to configure Write-Ahead Logging (WAL) mode for better concurrency during database operations.
- Ensured WAL mode is set only once, with error handling to fall back to default settings if configuration fails.
- Updated the migrateDb method to call the new configuration method on the first database operation.
