Add domain filter on x_fclk_nfc_kiosk_location_id so the dropdown
only shows locations belonging to the current company in multi-company
setups. Replace shared-company mutation in test with a fresh company
to prevent cross-test state leakage.

Adds x_fclk_nfc_kiosk_location_id (Many2one → fusion.clock.location) to
res.company so each company can designate which NFC kiosk location it uses.
Two tests cover field assignment and default-false behaviour.
