The file manager's decoded FCI shows the '8B' security attribute
reference (EF_ARR 2F06, record 23). The referenced record's access
rules are now rendered as indented muted lines under that row, decoded
with the existing EF.ARR record decoder (AM_DO/SC_DO conditions).
The server reads the card's ARR copies (MF/2F06 and ADF.USIM/6F06,
best effort) once per card session in _apply_equipped_card and keeps
them as server.arr; GET /api/arr serves the cache without the card
lock, a disconnect clears it, and a write to an ARR copy through
/api/write refreshes it. The PWA fetches it lazily per card session
(pysimArrEnsure, keyed by card_session) and resolves the reference with
the selected file's DF context: an ADF.USIM file uses the ADF's 6F06
copy, the implicit reference form too (ISO 7816-4 5.4.3.3 lookup
order). Unresolvable references stay silent.
The '8B' decode now covers all three ISO 7816-4 Table 25 forms:
implicit ARR byte / FID + record / FID + (SEID, ARR) pairs - the pairs
form was mis-decoded as a record before. A snapshot resolves the same
references offline from its own captured EF.ARR copy.
Tests: the three forms, the resolution (DF preference, out-of-range
silence), the snapshot path, the server read/cache/route/write-refresh.
