docs: sync help/help-ru with current UI, fix deep-link anchors

Audited both help files against the UI and fixed stale/missing content:

Fixed:
- Expanded Script: remove the nonexistent 'Response Type' TLV row; Error
  Action is 'one of four forms', not three
- 'Expanded Remote Response' section described a UI that does not exist;
  rewritten as response decoding (PoR shown in the Secured Packet view,
  last SW/data filled into the Response parser)
- Cards/Custom files: document all five export/import buttons
- Reader auto-detection: drop the stale /dev/ttyUSB0 start.sh bullet, fix
  'Reader: none' and the 'Equip card' button name, note the server-side
  PC/SC probe with retries
- Profiler: 'Check contents' label, symbolic names next to rule paths,
  Add rule/Save buttons, aligned read-only expected/actual fields for
  raw-data mismatches

Added:
- 1.1 Interface (header chrome: INSTALL PWA, github/help links, EN/RU and
  theme toggles, localStorage persistence, help deep-links)
- GPC v2.2 Amendment B v1.1 in the standards list
- Card reader connect workflow (URL, Connect, status, Equip card)
- File manager tree browser + Save/Cancel
- Send to Card PoR behavior in 3.1/4

Also fixed the app help anchors: C-APDU Parser now opens #c-apdu-parser
and the Profiler sub-tab opens #profiler. SW cache v60 -> v61.
