feat(admin): delete button on request link

The request-links panel now has a trash button at the far right of
each row. Click it, the link is gone — cascadeDelete on
intake_link_submissions.link removes the daily counters in the same
transaction, and revalidatePath re-renders the panel without the row.

Hard delete, no confirmation: matches the existing Pause/Resume
pattern (no dialog there either). The icon is a Trash2 from
lucide-react; the title attribute is the only label, by design
owner-only surface.

Phase 9 shape: action takes a scope so revalidation hits the
client admin page the panel is mounted on.
