Reusable 4-digit PIN pad. Auto-submits on the 4th digit via the
onSubmit prop. On wrong PIN, shake animation + dots clear + error
banner (caller controls the message via the returned {ok:false, error}).
Used by FpTabletLock (unlock flow) and FpPinSetup (set/change flow).
Dark-mode SCSS branch follows the same $o-webclient-color-scheme
pattern as the rest of the shopfloor components.
Also registers tech_store + activity_tracker services in the asset
bundle (assets/web.assets_backend) before the pin_pad files, since
the pin_pad/tablet_lock components consume them.
