feat(pilot): InlineNoTemplateDialog — chat-region placement wrapper

Slide-up wrapper around the existing NoTemplateDialog for rendering
in the chat region above the composer (parallel to ProposalBanner).
The chat region's width lets grid-cols-3 finally work as intended.

No change to NoTemplateDialog itself; decision callbacks and card
copy stay identical.
