fix(client): compose shared buttons for two disclosures and seed re-enabled ask drafts

Compose the shared Button for the memory-artifacts and web-search disclosure
rows, keeping only their geometry local. The web-search row keeps its instant
hover by suppressing the recipe's color transition, since the chevron beside it
reveals without a fade and the existing test pins that.

Seed the ask-specific draft when Save drafts is re-enabled. An answer captured
while saving was off has no persisted ask draft for autosave to restore, so
expanding opened an empty composer and the next collapse read that empty value
back over the in-memory answer.
