refactor(openflare): mount console APIs under /api/v1/openflare

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.
