feat(fusion_plating_shopfloor): FpPinSetup client action for self-service PIN (P6.2.6)

Registers fp_tablet_pin_setup as an ir.actions.client tag. Triggered
from res.users preferences via action_open_tablet_pin_setup (added
to res_users.py in P6.1.1). Three-stage flow:

  loading → check if user has existing PIN via search_count
  old     → enter current PIN (skipped if first-time)
  new     → choose new PIN
  confirm → enter new PIN again
  done    → success toast + auto-close 1.5s later

Each stage reuses FpPinPad with a different onSubmit + title. On
mismatch / server error, resets to the first stage with a notification.
