When a source is selected, a new card appears between the import action
controls and the progress panel showing all brands being imported from
that source as pill chips. Single-brand sources show just the name;
multi-brand sources show a count heading + all brand chips.
Styling: indigo pill chips with dark-mode support via
@media (prefers-color-scheme: dark). No external deps added.

action: handles _action=cancel by calling POST /pipeline/cancel/:jobId
UI:
- Start button disabled while a job is running for that source
- Cancel import button appears only when the active source has a
running job (status not in done/error/cancelled)
- Toast shown on cancel request confirming stop after current step
- runningSources excludes cancelled status so tab resets correctly
