Add FCC Carrier/ISP Registration: API, checkout, handler, dispatch

Phase 3-5:
- API: POST /api/v1/fcc-carrier-registration (order creation with pricing)
- API: GET /api/v1/fcc-carrier-registration/:id (status)
- API: GET /api/v1/fcc-carrier-registration/state-fees (formation fees)
- Checkout: fcc_carrier_registration order type with Stripe line items
- Payment handler: dispatch worker + send confirmation email
- Pipeline handler: 8-step CRTC-style pipeline (formation → CORES → 499 →
  DC Agent → State PUC → RMD/CPNI/CALEA/BDC → add-ons → final review)
- Job server dispatch map entry
- Service page CTA updated to link to order page
