Verifies PIN, resets failure counter on success, increments + locks out
on 5 consecutive failures (configurable via ir.config_parameter
fp.shopfloor.tablet_pin_fail_threshold + tablet_pin_fail_lockout_minutes,
both defaulting to 5).
Returns informative payloads:
ok=true current_tech_id, current_tech_name
needs_setup=true user has no PIN yet
locked_until lockout in effect (rejects even correct PIN)
attempts_remaining failed but not yet locked
Logs INFO on success, WARNING on failure (with running counter +
locked flag).
