Two view inheritances on res.users:
(a) Preferences form — adds a 'Tablet PIN' group with a 'Set / Change
Tablet PIN' button that triggers action_open_tablet_pin_setup → the
fp_tablet_pin_setup OWL client action (Phase 6.2). Shows PIN Last
Set as read-only context.
(b) Standard res.users form — header button 'Reset Tablet PIN' visible
only to the fusion_plating manager group; hidden when no PIN is set
(via the set_date invisible field reference). Confirms before clearing.
Calls the clear_tablet_pin method from the model.
