Add deeper command-body decoding: AUTHENTICATE, ENVELOPE, SM TPDU
- _decode_auth_cmd: AUTHENTICATE command body → RAND/AUTN (GSM/3G,
context from P2)
- EVENT_TYPES + event download decode (Event List → event name,
Location status → Normal/Limited/No service)
- _decode_envelope: D1 SMS-PP (SMSC + SMS TPDU), D2 Cell Broadcast
(structure), D5 MO SM control (SMSC + TP-DA + location), D3/D4/D7 basic
- _decode_sm_tpdu: SMS-DELIVER/SMS-SUBMIT → TP-MTI, BCD address, TP-PID,
TP-DCS (encoding + class), text (GSM 7-bit / UCS2 only; 8-bit stays
hex; PID 0x7F → secured packet hex)
- helpers: _decode_bcd_address, _decode_gsm7, GSM 7-bit alphabet
decode_message stores command-body decode in decoded.cmd for
AUTHENTICATE (0x88/0x89) and ENVELOPE (0xC2).
tests: 79 total (auth-cmd, event download, SM TPDU, BCD, GSM-7).
