fix(#206): read clarify.request question/choices from gateway (#355)

* fix(#206): read clarify.request question/choices from gateway

The Hermes TUI gateway sends clarify.request payloads with "question" and "choices" fields, but the Android parser was looking for "text" and "options" — so the text was always null and the dialog showed only the input box.

Fix reads "question"/"choices" first, falls back to "text"/"options" for backward compat.

Test added for the new field names; existing test for legacy names still passes.

* fix(#206): clear default text in clarify input field

The input box was pre-filled with the clarify question text because the initial state was set to clarify.text instead of empty string.

* fix: use JsonRpcResponse instead of undefined WsResponse in EventParserTest
