catarrh 6da5acca21 Decode C-APDU commands inside secured-packet payloads (frontend)
The secured data of an SCP80 packet is a stream of C-APDUs (e.g.
SELECT / UPDATE BINARY sequences for OTA file management). Vendor the
working C-APDU parser from the otaman project (frontend-only, ~10 KB):
PARSE_INS table, describeP1P2, describeInstallDataLv, parseOneApdu and
parseCompactApdus (concatenated streams with implied-CLA handling).

Detail view now shows an "Application message" section for secured
packets:
- unciphered packets (SPI1.b3=0): the on-wire secured data decodes
  immediately;
- ciphered packets: decodes from the client-side decrypted payload
  once the user supplies the key (before that, ciphertext rows only);
- each C-APDU renders as a numbered row with indented CLA/INS/P1/P2/
  Lc/Data/Le + descriptions (nested LV for INSTALL), with implied-CLA
  annotation; raw-hex fallback when nothing parses;
- vendored parser uppercases input (otaman's expects uppercase hex).

Tests deferred to the follow-up step (node:test infra, planned).
Version 1.20.0, SW cache simtrace-analyser-v28.
