QR "scan to connect" pairing has no wallet number, so nothing registered
the request with the relay and the scanning device's response was rejected
("unknown or expired request"). The backend now pre-registers the pairing
request over the relay's new hub:expect event on POST /pair, and
re-registers still-pending requests on hub (re)connect so routing survives
a relay restart. /pair now requires the clinic to have joined the network
(clear 409, surfaced in the import dialog, localized in all five langs).

- Backend: nullable wallet_number on wallet_share_requests (migration 0029);
createPairingRequest + POST /api/patients/wallet/pair; applyShareResponse
binds the authenticated wallet on QR (pairing) requests
- Frontend: Import dialog gains a "Show QR" mode rendering a temetro-pair QR
(react-qr-code) the patient scans; requestWalletPairing helper; i18n keys
