feat(ui): show last activity table on consumer edit page

Adds a "Last activity" section at the bottom of the consumer edit
page showing the 10 most recent audit log entries scoped to this
consumer (entity_type=consumer, entity_id=<id>). Each row can expand
to reveal the change diff or raw payload, and a "View all in audit
log" link jumps to the audit page pre-filtered by the same consumer.

The audit lookup is best-effort — if the audit endpoint fails the
edit form still renders.

Note: blocklist fetches are not currently audited, so this surfaces
admin actions on the consumer record (created / updated / deleted)
rather than per-fetch consumption events.
