Extended logical channels: CLA 0-19, ATR card capabilities, MANAGE CHANNEL (v2.6.0)

- CLA decode (TS 102 221 §10.1.1/§10.3): standard channels 0-3 from b2-b1
  and the extended channels 4-19 from b4-b1.  The old further-format rule
  read only b2-b1 (channel 8 read as 6, 19 as 7) and the ETSI '11x0 xxxx'
  coding (0xC0-0xEF) was not handled at all; the class ranges now follow the
  specs (0x80-0x8F UICC, 0xA0-0xAF SIM, 0xC0-0xEF ETSI extended, 0x20-0x3F
  reserved, 0xFF invalid) and SM/chain are decoded per family — the SM
  extraction and the chaining bit (b5, not b6) were off by one bit
- per-channel state: database._decode_rows/_replay_context use the shared
  cla_channel() helper — before, CLA & 0x03 with no +4, so a channel-5
  SELECT clobbered channel 1's selection and a channel-8 one channel 0's
  (the local traces already open channels: 29 MANAGE CHANNEL opens, 1-2)
- COMPRION T=0 import: the synthesized GET RESPONSE keeps the channel —
  a plain CLA for 0-3 (as real terminals do) and 01x0 for 4-19
- ATR historical bytes: the UICC's COMPACT-TLV objects (TS 102 221 §6.3.1)
  with card service data, the card capabilities (ISO 7816-4 §8.1.1.2.7
  Table 88: assignment methods and max logical channels — the workspace
  cards announce 4 and "8 or more") and the status indicator ('00' trailing
  bytes / the '8Y' TLV); a truncated ATR no longer raises
- MANAGE CHANNEL success replies decode the assigned channel byte
- capture/import: a 'tpdu' packet that is not APDU-shaped (shorter than the
  header, CLA FF, ISO-reserved class) is skipped and counted, so a
  character-level or mis-sampled stream no longer pollutes the decode
  (the local DB's outlier sessions are exactly that)
- tests: CLA table vectors, per-channel state isolation on channels 8/12,
  COMPRION GR channels, filetrack extended channels, ATR compact-TLV and
  card-capability cases, the capture skip counter, the PWA rows; 527 Python
  + 47 Node tests
- README/README_RUS document the extended channels, card capabilities and
  the skip counter; PWA_VERSION/pyproject/version.py 2.6.0, SW v72
