## Summary
This PR updates backend service-session orchestration so
interview, roleplay, resume, and matchmaking flows integrate with
the shipped `workflows--dashboard` frontend instead of the old
GrowQR app demo UI.
## Changes
- Added `WORKFLOWS_DASHBOARD_URL` config with fallback to
`FRONTEND_ORIGIN`.
- Updated service session URL generation to point to dashboard-
owned routes:
- `/v2/service-sessions/interview`
- `/v2/service-sessions/roleplay`
- `/v2/service-sessions/resume`
- Preserved session query params, including `session_id`, service
id, and user-facing metadata.
- Updated chat route handling so returned service cards include
dashboard session URLs.
- Added/updated matchmaking service integration wiring.
- Documented the dashboard-owned session route behavior in
## Validation
- `npm run build` passed for `growqr-backend`.
