"""Sales rep portal for repair intake.

Sales reps marked `is_sales_rep_portal` on their partner can:
- /my/repair/new          - submit a new service call from their phone
- /my/repairs             - list of repairs they have submitted
- /my/repair/<id>         - read-only detail with status timeline

All routes are gated by the is_sales_rep_portal flag and use the SAME
shared intake service (`fusion.repair.intake.service`) as the backend
wizard - so behaviour stays consistent across surfaces.
