test(desktop): trim kanban scope tests to their invariants

Store test header points at the store/connections.ts comment instead of
restating it; drop the two assertions implied by the final-tag check; drawer
test invalidates via taskKey() instead of a raw prefix literal. Revert the
comment-style churn on the unrelated $activeConnectionProfile subscription.
