fix: keep suggested questions reachable, simplify sources control, fix dark-mode logo contrast

Adds a persistent chip strip above the chat input so business-question
suggestions stay clickable after the first message instead of disappearing,
merges the header's source-count pill and Edit sources button into one
control, and fixes disabled database-type logos being nearly invisible in
dark mode by extending the existing .knowledge-surface dark override.
