feat(resolvespec): accept bunrouter.Router and bunrouter.Group in SetupBunRouterRoutes

Replaced *router.StandardBunRouterAdapter parameter with BunRouterHandler
interface to support both bunrouter.Router and bunrouter.Group types,
enabling route registration on router groups with path prefixes.

- Added BunRouterHandler interface
- Updated SetupBunRouterRoutes signature
- Updated example functions to use bunrouter.New() directly
- Added ExampleBunRouterWithGroup demonstrating group usage
