refactor(openflare): migrate console APIs to v1 and centralize routing

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
