feat(fusion_repairs): Bundle 1 - wizard polish (C1 + C5 + C6 + D2 + T1)

C1 duplicate-call detection
- Wizard computes duplicate_count + duplicate_repair_ids when partner is
  picked (open repairs from the configurable window, default 14 days).
- Yellow banner with "Open Existing Repair" button to jump to the most
  recent duplicate so CS can add a note instead of creating a new repair.

C5 outstanding-balance warning
- Wizard sums posted unpaid account.move.amount_residual across all
  invoices of the partner.
- Red banner shown when balance >= fusion_repairs.outstanding_balance_threshold
  (default $100) with a "View Invoices" button.

C6 quote-only mode
- New quote_only boolean on the wizard; passed through the shared intake
  service. Skips dispatch-task creation for urgent/safety AND for catalogue
  auto_schedule. Chatter note "Created in Quote Only mode" posted on the
  resulting repair.order.

D2 skills filter on dispatch picker
- _pick_dispatch_technician(repair) prefers users whose x_fc_repair_skills
  Many2many contains the repair's product category. Three-tier preference:
  1) intake user if field staff AND has the skill
  2) any active field-staff user with the skill
  3) any active field-staff user (no skill filter) - last-resort
- Logs a warning + skips task creation if no field-staff user exists at all.

T1 Open in Maps on technician task
- action_open_in_maps() returns ir.actions.act_url to
  https://www.google.com/maps?q=<URL-encoded address>. Deep-links into
  Apple Maps / Google Maps native apps on iOS / Android, browser otherwise.
- Header button added on the fusion.technician.task form (after the
  existing buttons) plus a "View Repair" button when x_fc_repair_order_id
  is set.

Verified end-to-end on local westin-v19:
  Existing repair: RO-202605-06
  C1 duplicate_count = 5 (>=1 expected) - last duplicate: RO-202605-06
  C5 balance check ran without error (target partner had $0)
  C6 quote-only repair: RO-202605-07 tech_tasks = 0 (expected 0)
  D2 picked the only stairlift-skilled field-staff user
  T1 Maps URL: https://www.google.com/maps?q=15+Fisherman+Dr%2C+Brampton%2C+ON+L7A+1B7%2C+Canad...

Bumped to 19.0.1.1.0.
