sigrok-iso7816-stream sets GSMTAP_FLAG_BAD_FCS (0x01) in the GSMTAP header `res` byte on desynced TPDUs (mis-framed exchanges kept for forensics). Propagate that flag through the whole pipeline so such packets are explicitly surfaced instead of decoding as garbage: - gsmtap.py: GSMTAP_FLAG_BAD_FCS const; GsmtapReceiver.read_packet() now returns (sub_type, data, flags) from the res byte. - server/capture.py: GsmtapListener forwards the flags to the DB. - pcap.py: _parse_gsmtap_hdr/_scan_gsmtap/extract_gsmtap and parse_pcap/parse_pcapng now yield a (ts, type, payload, flags) tuple, so the flag survives a PCAP/PCAPNG round-trip. - server/server.py: PCAP import stores the flags. - server/decode.py: gsmtap_flag_names() maps bit 0x01 to 'bad FCS (desynced)'; merged into decoded errors for tpdu/atr/pps and rst/vcc, so the frontend ⚠ badge + Errors row flag the entry. User-visible: desynced TPDUs show a ⚠ "bad FCS (desynced)" marker in the trace and detail views. Tests: +4 (decode BAD_FCS markers, PCAP flag round-trip); existing tests updated for the new tuple arities. Version 1.22.0, SW cache simtrace-analyser-v32.
