Move OpenFlare route registration from RegisterCustomRoutes to
v1.RegisterV1Routes so business APIs are mounted directly at
/api/v1/openflare instead of under the /custom example prefix.
Update handler Swagger annotations, frontend service base paths,
and regenerated swagger docs accordingly.
Move OpenFlare management endpoints to /api/v1/custom/openflare with
Wavelet response envelopes and Abort* error handling. Keep agent, relay,
and flared protocol routes on /api/* with the legacy compat format.
- Add apiutil helpers and Swagger annotations for console handlers
- Register all OpenFlare routes in internal/router/openflare (not apps)
- Switch frontend services to OpenFlareBaseService and v1 paths
- Remove dead auth/compat code and legacy-base.service.ts
- Update integration tests and changelog
