fix(clients): list HWID devices when the HWID limit is 0

Browse Source 
EnforceHwidForSubID returned before recording anything when a sub had no
limit, so the panel's HWID Devices list stayed empty for every unlimited
client. Devices are now upserted on the (sub_id, hwid_hash) index without
enforcement or X-Hwid-* headers; the write is best-effort and only logs on
failure, so tracking can never deny a subscription nothing restricts.
