feat(fusion_plating_shopfloor): station roster + idle override + tablet config defaults (P6.1.6)

Adds two fields to fusion.plating.shopfloor.station:
- x_fc_authorised_user_ids (Many2many → res.users): restricts the
  tablet lock-screen tile grid to a specific roster per station.
  Empty = all operator-group users shown.
- x_fc_idle_lock_minutes (Integer, nullable): per-station override
  for the auto-lock idle threshold; null = use system parameter.

Plus data/fp_tablet_config_data.xml registers four ir.config_parameter
defaults (noupdate=1 — manager can override via Settings → Technical
→ Parameters):
  fp.shopfloor.tablet_idle_lock_minutes = 5
  fp.shopfloor.tablet_pin_fail_threshold = 5
  fp.shopfloor.tablet_pin_fail_lockout_minutes = 5
  fp.shopfloor.tablet_warn_seconds_before_lock = 30

Form view surfaces both new fields in a dedicated 'Tablet PIN Gate'
group.
