fix(ui-user-questions): label every copy toggle Expand or Collapse

Option names made the toggle tooltips as long and unpredictable as the
option labels themselves. Every question and description toggle now uses
the same Expand and Collapse copy, and the question toggle, like the
description toggles, is described by the text it controls.

 ### Answering
 
-A multi-select draft keeps its selected labels while the user opens or edits the custom answer, so its submitted item may carry both `selected` and `custom`; a single-select custom answer remains exclusive. Question detail reuses the assistant-output `MarkdownText` primitive, including its GFM rendering and untrusted-content policy. The capped card keeps navigation and submission actions fixed while the question, long detail, and choices share an internal scroll region. A question appears in full up to three rendered lines; a longer one shows two, fades at the end of the second, and places a downward-chevron expand button there that expands it in place. Option descriptions use 13px text with a 20px line height and sit beside their label when they fit, otherwise below it; a description appears in full up to two lines, and a longer one shows one line with the same fade and expand button. Expanded copy keeps an upward-chevron collapse button on a line below it. Both buttons carry a localized accessible name and a hover tooltip. CSS scroll timelines decide which copy overflows; a browser without them shows all copy in full. "Skip" retains other drafts and emits the existing blank `{ selected: [] }` result for that item. Close is not an answer: a question the Host named by tool call only leaves the composer seat, and its `ask_user_question` tool call row brings the panel back; a request that carries no tool call has no row to return from, so closing it rejects the whole wait as `ASK_CANCELLED`.
