gsinghpal 73ee48e7c9 feat(fusion_repairs): Phase 3 - maintenance contracts + client self-booking ...

Maintenance contracts
- New fusion.repair.maintenance.contract model: one per partner +
  product + lot. Fields: interval_months, last_service_date,
  next_due_date, state, booking_token (secrets.token_urlsafe),
  last_reminder_band (30 / 7 / 1), booking_repair_id
- roll_next_due_date() advances the cycle by interval_months and resets
  the band / booked-repair so the next cycle starts fresh
- sale.order._spawn_maintenance_contracts() creates contracts for
  delivered SOs whose product has x_fc_maintenance_interval_months > 0
  (called from Phase 3 hooks; ready for cron / on-state change wiring)

Reminder cron
- Daily ir.cron at 07:00 -> cron_send_due_reminders()
- Sends email at 30 / 7 / 1 day bands before next_due_date; tracks
  last_reminder_band so we never re-send the same band in one cycle
- Master toggle via ir.config_parameter fusion_repairs.enable_email_notifications

Public client booking portal
- /repairs/maintenance/book/<token>  GET landing page with a date input
- /repairs/maintenance/book/<token>/confirm  POST creates a repair.order
  via contract.create_repair_from_booking() (source='client_portal')
- Idempotent: existing booking shows "already booked" instead of
  spawning a duplicate
- Invalid / expired tokens render a friendly "link not valid" page

Mail template
- email_template_maintenance_due_reminder with 4px green accent bar,
  600px max-width, dark/light safe; renders the tokenized booking CTA
  button directly to /repairs/maintenance/book/<token>

Backend
- Maintenance Contracts list / form with statusbar + chatter
- Menu under Operations -> Maintenance Contracts
- Sequence MC/##### for contract reference
- Access rules: User read, Dispatcher write, Manager full

Verified end-to-end on local westin-v19:
- Contract MC/00003 created due in 7 days
- cron_send_due_reminders() fires the 7-day band; second invocation
  skips (idempotent)
- create_repair_from_booking() spawns BR-WA/RO/00014 with
  x_fc_intake_source='client_portal' and links it back to the contract
- HTTP GET /repairs/maintenance/book/<token> -> 200 with the date input
  and contract reference visible in the page
