For SDR backends, DIG and PKT are removed from supported_modes and replaced by USB and FM respectively. CAT backends (FT-817, FT-450D) retain DIG/PKT as before. Decoder mode allowances updated: - APRS: FM | PKT (was PKT only) - HF-APRS: USB | DIG (was DIG only) - AIS: AIS | FM | PKT (was AIS only) - VDES: VDES | FM (was VDES only) - FT8/FT4/FT2/WSPR: USB | DIG (unchanged) - CW: CW | CWR (unchanged) - LRPT: FM (unchanged, mode-independent) Frontend status text, bookmark decoder toggles, background-decode fallbacks, and scheduler wiring updated to match. https://claude.ai/code/session_01DCAaMH8RF5FNB2gRtVu4pY Signed-off-by: Claude <noreply@anthropic.com>
