v3.32.7: drop the pySim JSON disclosure from the file manager

The decoded view is the client-side EF decoder's table over the raw
read's bytes.  The collapsed "pySim JSON (server)" block was an
unrelated second decode - opening it ran another /api/read with mode
'decoded' (pySim's read_binary_decoded/read_records_decoded on the
card) - and it existed only when our decoder covered the file, so it
could not serve as a cross-check where one would matter.

/api/read keeps mode 'decoded' for API callers.  Help, READMEs and the
project notes now state the table is built in the browser from the same
raw bytes; ef_decode.test.js pins the view's output and that no
mode 'decoded' read remains in the PWA.

 Browse the UICC filesystem in a tree view. Files are shown with names, FIDs, and AIDs (for ADFs). Selecting a file shows its detail pane: FID, file type, size / record layout and the decoded FCI (in a bordered block labelled with the file's symbolic name) above the content pane. When the FCI references its access rules through an EF.ARR record (security attribute `8B`), the referenced record's decoded rules are shown as indented lines under that row — resolved from the card's cached EF.ARR copies (MF, DF.TELECOM/DF.GSM and ADF.USIM, following the file's DF chain; a snapshot resolves them from its own captured copy).
 
 - 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 server-side pySim JSON of the same read stays behind a collapsed *pySim JSON (server)* disclosure; **Read decoded** is disabled when the client-side decoders do not cover the file (resolved by name/FID before reading)
+- **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. The decoded view is read-only — **Edit raw** switches to the hex view first and reads the file if needed
 - **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
