feat: TAR probe becomes its own SCP80 pill with a TAR checklist (v3.8.0)

The probe is not a RAM operation, so it moves out of the RAM view into a third
SCP80 pill (Secured packet | RAM | TAR probe, RU "TAR-сканер"), with its own
preset and key-version selectors, its own equipped-card mismatch banner and its
own result line; the help gains a "3.3 TAR probe" section and the anchor map
follows the pill.

The TAR field is a checklist now: pre-populated with the standard allocations
of TS 101 220 V18.3.0 Annex D, Table D.1 (each row carrying the document it
comes from, all checked by default, Select all / Select none), plus custom
TARs added through a small form (three hex bytes + an optional description,
removed with a x).  Custom entries live in localStorage['simple_tar_probe'] on
a best-effort basis - losing them is harmless, the standard list is always
there.  Only the checked TARs are sent; nothing checked is refused with a
message.  A Python test guards the PWA's list against the server's
TAR_PROBE_TARS (the endpoint keeps its own default for API callers).

RAM leftovers removed (the tar-probe operation entry, the #ram-tar-rows block,
the ramExecute dispatch, ramTarProbe); getRamSpParams() takes the view's
selector id; tarRender/tarApplyCard/tarKeysetChanged/tarKeysetGuard mirror the
RAM view; spKeysetSync and spPresetWarningRender cover the new selectors.
sw cache simple-v338.  Tests: 740 Node (the checklist rows, the custom
round-trip, the checked-list read, the renderer, the pill wiring) and 619
Python (the list drift guard).
