scp81 passthru, proactive decoders, ADM badge, file manager layout (v2.2.1)

SCP81:
- New listener mode "passthru": no local listener - the card's BIP
  channels connect straight to a configured external platform
  (host/port required), which terminates TLS and runs the dialog.
  The status API reports mode/target (_SCP81_MODE/_SCP81_TARGET) and
  clears them on stop. PWA mode select, hint, Start validation; TLS PSK
  stays the default.

Proactive command decoding (Phone tab log):
- SEND SHORT MESSAGE (0x13) is now decoded: alpha, address (TON/NPI +
  number), 3GPP-SMS TPDU (type, TP-MR, TP-DA, TP-PID 0x7F flagged as
  SIM data download, TP-DCS, TP-VP, TP-UDL), UDH concatenation IEs, and
  the TP-UD as text (GSM-7 with a septet unpacker, UCS2, 8-bit) or as a
  TS 31.115 secured packet for PID 0x7F; malformed TPDUs fall back to
  the raw hex line.
- PROVIDE LOCAL INFORMATION qualifier names completed per TS 102 223
  V18.3.0: ESN (07), MEID (0B), Supported RATs (1A); 05 relabelled
  "Reserved for GSM (Timing Advance)". Fixed in the server dict and
  both frontend tables.

Header:
- Compact ADM badge next to the card indicator: "ADM ✓" green when
  pySim's adm_verified is set, "ADM ✗" red otherwise, hidden without a
  card session or when the server is down; updated ahead of the card
  state-key early return so it never disturbs the connect/reset flow.

File manager:
- Sort pills (FID/Name), Probe all files button and progress line are
  pinned above the tree instead of scrolling with it; the tree box cap
  grows from 420px to 65vh.

SW cache otaman-v165; help EN/RU updated; tests 234 Python + 361 frontend.
