perf: self-host fonts, drop unused generated code and add swf tests

- Self-host Nunito and Pixelify Sans via next/font instead of Google Fonts CDN
  (removes render-blocking external stylesheets and preconnects)
- Remove stale mariadb entry from serverExternalPackages (app uses mysql2)
- Exclude unused src/generated Prisma client from typecheck and remove it
- Add unit tests for swf-parser, effectmap and figuremap (0% coverage -> 90%+)
