feat(fusion_repairs): Bundle 7 - tech mobile (T3 + T4 + T6 + T7)

T3 Labour timer on technician task
- Two new fields on fusion.technician.task: x_fc_timer_running_since
  (Datetime) + x_fc_timer_accumulated_minutes (Float).
- action_timer_start / action_timer_stop methods, idempotent (start when
  already running is a no-op, stop when not running is a no-op).
- Multiple start/stop cycles accumulate into the same total.
- Two header buttons (Start Timer green / Stop Timer amber), invisible
  based on the running_since field so the right one shows at any time.
- Stop posts a chatter line 'Labour timer stopped. Added X.X min, total
  Y.Y min.' so audit history shows every shift.

T4 Client signature on visit report
- New client_signature Binary field on the visit-report wizard with
  Odoo native widget='signature' that draws on canvas + base64-encodes
  the PNG.
- client_signature_name Char for typed name (audit).
- Persisted as an ir.attachment on the repair.order via the new
  _persist_mobile_artefacts helper.
- Chatter post 'Client signature captured (Jane Smith).'.

T6 Replaced parts - serial capture
- parts_serial_capture Text on the wizard (one per line per the spec).
- On confirm, posted to chatter wrapped in <pre> so line breaks survive.
- Used by OEM warranty filing in future M8.

T7 Client no-show photo proof
- no_show Boolean + no_show_photo Binary with widget='image' (visible
  only when no_show=True via Odoo 19 invisible= conditional).
- Photo saved as ir.attachment on the repair when present.
- Chatter post 'Visit recorded as client no-show (photo attached)'.

Verified end-to-end on local westin-v19:
  T3 timer started -> 2s sleep -> stopped -> 0.0357 min recorded
  T4 attachment 'signature-RO-202605-17.png' created on repair
  T6 chatter shows 'SN-AAA-111 / SN-BBB-222'
  T4 chatter shows 'Client signature captured (Jane Smith)'

Bumped to 19.0.1.7.0.
