catarrh 9e85f522f6 fix: recover the SMS-SUBMIT listings in RAM Explore (v3.6.4)
Explore returned partial data (no ELF/module entries, the installed package
missing) and then failed with cntr_low.  Two causes, both in the
actual-response SMS-SUBMIT path the card uses for big listings:

- `_find_sms_tpdu` read TLV lengths as a single byte; the FETCH carries
  `8B 81 97 ...` (BER long form) for the big pages, so it returned a
  corrupted, truncated TPDU.
- `_calc_ud_offset` treated the SMS-SUBMIT relative validity period (VPF=10)
  as 7 bytes instead of 1, shifting the UD offset: `_parse_sms_concat` then
  read a bogus UDH and reported no concatenation, so the segments never
  assembled and the PoR/data was dropped ("RAM RESPONSE-PACKET: empty").
  The step was marked failed, the counter did not advance, the same counter
  was retried and the card answered `cntr_low`, which also blocked P1=10
  (modules) where the installed package appears.

- the captured segments now always store the assembled UD (`submit_ud_hex`);
  `_sms_submit_por()` rebuilds the DELIVER-style packet (`02 71 00` + UD) for
  `_decode_por`.  Verified against the live capture: por_ok, remote SW 6310,
  438 hex chars of listing data (the exact bytes of the P1=20 page).
- `spPorAccepted` counts `actual_response_sms_submit` (0x0B) as accepted, so
  the counter advances when the data follows via SMS-SUBMIT.

Explore queries follow GP Card Spec v2.3.1 11.4.2.2: compact listings
(P2.b2=0) with the chained GET RESPONSE (`ramGetStatusApdu`, paging P2=00 ->
P2=01), the malformed P2=02 attempt is gone, and the ISD-only query (P1=80)
never pages with next-occurrence (the card shall reject it).

Tests: Python SmsSubmitCaptureTest with the live FETCH bytes (TPDU length,
UD offset, concat reassembly, 027100+UD decode); ram.test.js checks the APDU
builder and the missing P2=02 attempt; cards_counter covers 0x0B.
