ui: regroup tabs — Remote APDU, Card reader, Profiler, Phone simulator

- C-APDU tab renamed Remote APDU (label untranslated EN/RU); Response
  parser moved from a top-level tab to a pill under it
- Profiler moved from the Card reader sub-tabs to a top-level tab
- Proactive UICC moved to a top-level tab and renamed Phone simulator
- Card reader keeps File manager, Custom files, pySim command line,
  Raw APDU
- modals (event send, profiler scan/snapshot, STK menu) moved outside
  the tab containers so they can open from any tab
- STK overlay disables the top-level tabs while waiting for user input
- OTA PoR jump now goes to Remote APDU > Response parser
- help EN/RU restructured (2.8 Response parser, 5 Profiler, 6 Phone
  simulator, subsequent sections renumbered, anchors kept); READMEs and
  AGENTS.md updated
- html.test.js asserts the new tab/pill structure; SW cache v92 -> v93
