ui: Parser pill — C-APDU / R-APDU parsers as sub-pills; R-APDU rename (v3.5.0)

Remote APDU now has six top-level pills (SIM RFM, USIM RFM, RAM/GP,
Expanded Script, Push commands, Parser); the C-APDU and R-APDU parsers are
nested panels behind the Parser pill, switched by parserSwitchSubtab().

- "Response parser" renamed to "R-APDU parser" (RU: «Разбор R-APDU»), the
  umbrella is "Parser" / «Разбор»; the C-APDU panel keeps its id and label.
- cApduSwitchSubtab() routes nested names through the Parser pill first, so
  pysimSendOta()'s post-send jump keeps working; the help deep-link anchor
  follows the selected parser (c-apdu-parser / response-parser) and the Push
  commands pill now links to the renamed #push-commands section.
- The small C-APDU panel moved next to the R-APDU panel so both live in the
  #c-apdu-sub-parser container; html.test.js checks the nesting and sub-pills.
- Pill lists updated in help EN/RU (2.6 note, 2.8 heading), READMEs, AGENTS;
  sw cache -> simple-v248.
