Update to version 2.2.0-alpha-2 and add database query provider

Bumped project version to `2.2.0-alpha-2` in `build.gradle.kts`. Introduced `SampleEntity`, `SamplePartEntity`, and `SampleEntityQueryProvider` for database handling. Added `SampleDao` with a sample query function. Updated SVG utilities with a `viewbox` extension and enhanced `RequestHandler` to set content type for HTML responses.
