v3.13.0: the Simulator's event forms honour the preset's CAT release

The consumption half of the release guard: the event-download forms hide the
parameters introduced after the effective release and say so.

- catEffectiveReleaseInfo(cards, iccid): the equipped card's preset (ICCID
  match, the same rule the SCP80 views use) resolved through presetRelease(),
  else the default Rel-12.
- eventFieldsForRelease(cfg, rel): a field whose introduction release (`rel`)
  is above the effective one is hidden; a field without a known release is
  never hidden.  The EVENT_FORMS annotations verified against the pinned
  specs/histories: the MT call IMS URI (Rel-12, CR 12.4.0 "URI support in MT
  Call event"), the CSG cell selection PLMN ID (Rel-12, 12.1.0), the IMS
  registration IMPU list + status code (Rel-11), the slices S-NSSAI-mapping
  and rejected objects (Rel-18).
- The form notes what was hidden: "hidden parameters: N · introduced after
  Rel-12 · preset: X" (or "default release"), with a tooltip naming the
  source; the send path already skips absent fields, so no builder changes.
