Place driver resource files here.

Recommended structure:
- service/internal/common/databases/drivers/resources/mysql/v8/logo.png
- service/internal/common/databases/drivers/resources/postgres/v13/logo.png

The server exposes these files under `/static/drivers/<dbtype>/<version>/logo.png`.
Drivers can register resource metadata using `drivers.RegisterDriverResource` to expose `LogoPath` and display name.
