feat(fusion_repairs): Phase 1 MVP - backend intake wizard + core models

Scaffolds the fusion_repairs module that extends Odoo 19 repair.order with
a guided medical-equipment intake workflow.

Models
- fusion.repair.product.category (8 medical equipment categories seeded)
- fusion.repair.intake.template / .question / .answer (7 templates,
  32 questions seeded across hospital bed, stairlift, porch lift,
  wheelchair, walker/rollator, mattress)
- fusion.repair.intake.service (AbstractModel) - single entry point used
  by backend wizard, sales rep portal, and public client portal so all
  three surfaces produce identical outcomes
- repair.order extensions (x_fc_intake_*, x_fc_third_party_equipment,
  x_fc_photo_ids, x_fc_urgency, x_fc_estimated/actual_cost, AI summary)
- fusion.technician.task back-link (x_fc_repair_order_id)
- res.partner service preferences (preferred tech, time window, access notes)
- res.users repair extensions (skills, cost rate, on-call rotation fields)
- res.config.settings for variance thresholds, portal URL, rate limit

UI
- Backend intake wizard with multi-equipment loop, third-party flag, photos
- repair.order form: Intake tab, Photos, Pricing tab, AI tab, smart buttons
  (technician tasks, intake answers, original SO)
- Kanban + list view urgency badges
- Fusion Repairs app menu (New Service Call, Repair Orders, Config)

Activities & Email
- 4 follow-up activity types (CS callback, tech dispatch, visit follow-up,
  manager review) with urgency-tiered deadlines
- 2 mail templates (client confirmation + office notification) with the
  same dark/light-safe styling as fusion_claims ADP templates

Security
- New res.groups.privilege + 3 groups (User, Dispatcher, Manager)
- Reuses fusion_tasks.group_field_technician (do NOT recreate)
- Reuses fusion_authorizer_portal.group_sales_rep_portal
- Multi-company global rule + technician scoping rule on repair.order

Verified end-to-end on local westin-v19 dev DB via odoo-shell - creates
multiple repairs in one session, auto-creates dispatch task for urgent,
attaches 4 activity types correctly per urgency tier and third-party flag.
