feat(fusion_clock): NFC tap endpoint (happy path)

Add /fusion_clock/kiosk/nfc/tap JSON-RPC endpoint that toggles attendance
via _attendance_action_change, writing x_fclk_clock_source='nfc_kiosk' and
location on clock-in, applying break deduction/penalty checks on clock-out.
Add 2 HttpCase tests (clock-in + clock-out with 6s debounce sleep).
