refactor(client): make one control move a question between chat and composer

The popover carried both a chevron and a close button. Both left the
question pending and both moved it into the chat, so their only real
difference was invisible: the chevron kept the composer wired up as the
answer box while the close button released it. Two icons for one visible
outcome, with the meaning hidden in a placeholder change somewhere else.

Collapsing now does both jobs at once. Moving a question to the chat hands
the composer back for normal messages, and the card's chevron re-arms it,
so the popover's visibility and the composer's role can never disagree.
Escape maps to the same path and the dismissed-ids state is gone. Both
chevrons get a tooltip and a matching label, since no glyph conveys this.

Also fixes two behaviours found along the way: the card's Skip was a
silent no-op once the question left the popover, because it routed through
a helper gated on answer mode instead of the live pause, and clicking a
multi-select row moved the keyboard highlight, leaving a row painted as
selected after it was unchecked.
