svatantrya 5ec2b79d03 core+gui: BBQR-only QR transfer, disable Audio when modem plugin unavailable
- 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).

"""
Tests for ``bal.core.animated_qr`` (BBQR interop).
Validates the self-contained BBQR codec against round trips, out-of-order
assembly, compression default/fallback, malformed-input rejection and the
format detection / parse_for_detection helpers.
Run:
source electrum/env/bin/activate
