v3.35.0: EF.SMSP decoded editor (the full SMS-parameter form)

TS 31.102 4.2.27 scope: alpha; TP-DA and TS-SCA with their own length
conventions (DA = digits, SCA = octets, 0 = default SMSC) and a TON
select; TP-PID; TP-DCS with TS 23.038 hints; the relative TP-VP with the
TS 23.040 ladder; a per-parameter "absent (the ME default applies)"
state.  Unchanged slots are copied verbatim (the live fixture's
DCS-absent 00 and present VP FF survive), alphanumeric TON-5 addresses
stay read-only, and every checked record is validated before any write.

Decoder fixes: the parameter-indicator bits were shifted (SCA on 5,
PID on 2, DCS on 3, VP on 4; the spec is DA/SCA/PID/DCS/VP on bits 1-5
with 6-8 reserved, 1 = absent), and the TP-DA length was read as octets
instead of digits (TS 23.040 9.1.2.5).

Live fixture: ffffffffffffffffffffffffffe9ffffffffffffffffffffffff07919733824009f0ffffffff0000ff
(SCA +79332804900, PID 00, DCS absent/00, VP FF) round-trips
byte-identically.

1022 Python + 1058 frontend green; simple-v468.

 - Entries are grouped with DFs above EFs and sorted by **FID** or symbolic **Name** (pills pinned above the tree together with **Probe all files**, remembered in `localStorage`)
 - **Read raw** / **Read decoded** — read the selected file as a hex dump or as a decoded field table (client-side decoders for IMSI, ICCID, SPN, PLMN lists, LOCI/EPSLOCI, ADN/MSISDN, service tables, SUME, …); the highlighted pill is the current view and clicking either pill (re-)reads the file. The decoded table is built in the browser from the same raw bytes (no server-side decode); **Read decoded** is disabled when the client-side decoders do not cover the file (resolved by name/FID before reading)
 - **Edit raw** — edit the raw hex data and **Save** to write back (or **Cancel**); transparent files use a textarea, record files one input per record with selection checkboxes. **Edit raw** switches to the hex view first and reads the file if needed
-- **Edit decoded** — edit through the file's own decoded form (client-side encoders; written via the normal update path): **EF.SPN**, **EF.PNN**, the PLMN lists **PLMNsel / FPLMN / EHPLMN** and **PLMNwAcT / OPLMNwAcT / HPLMNwAcT**, the dialling-number files **ADN / FDN / SDN / MSISDN / LND / BDN**, the service tables **UST / IST / EST** (**SST** stays read-only until the SIM allocated/activated editor exists), **ACC**, **PHASE**, **HPPLMN**, **AD**, **ICCID / IMSI** (behind a confirmation), and the cell-broadcast lists **CBMI / CBMID / CBMIR**. Transparent files get one form (PLMN rows and PNN items with add/remove); record files get one form per record with a checkbox that is auto-checked when a field changes, so only edited records are written. **Save** validates every selected record before writing; extension pointers (EF.EXT1–EF.EXT5) and the BDN comparison-method byte are preserved, and editing a number continued in an extension file is refused. The shape survey and the planned coverage are in `docs/decoded-editing.md`

 - **Probe all files** — walks the whole tree (incl. custom files), marks every entry present/absent with *N / total* progress, stoppable, and ends with a summary; browsing itself stays lazy. Missing files are shown in red (✗); a present but empty DF shows `(empty)`
 - **ADM** — files that need the administrator PIN fail with `6982`/`9804`; when the matching card preset (same ICCID) carries an ADM key, a **Verify ADM** button appears next to the error and the header badge (`ADM ✓/✗ ⚿`) becomes clickable. Every wrong key consumes an attempt (the remaining attempts are shown and a retry asks for confirmation); a blocked ADM needs the card's unblock key
