The literal '%' in "100% of wallet balance" was detected as a Python
format specifier (%o in English vs %d in the translations), so
pybabel compile failed and the catalogs could not be built. Reword to
put '100%' at the end of the sentence and refresh es_ES/it_IT.
- Drop BALQR / BC-UR v1 / v2 wire formats, keep BBQR only (animated_qr,
qrtransfer, dialogs); remove the settings "QR Code Size" selector and
persist the export-dialog size choice instead.
- Disable the Audio transport radio button in the import/export dialogs
when the audio_modem plugin (or its amodem dependency) is unavailable.
- Refresh translation catalogs (bal.pot, es_ES, it_IT).
