frontend: scan a patient's wallet code in Import from a patient app

Adds a Scan button beside the wallet-number field in the import dialog,
reusing the BarcodeScanner. A scanned QR or 2D barcode from the patient's
wallet app drops the wallet number straight into the field. i18n added to
all locales.
