+ * Activity tab content for the ProviderDrawer (SP21 Task 3.1).
+ *
+ * STUB — renders the top-10 `recent_activity` events as a flat list
+ * (`ts` + `kind`). Real activity-event routing (linking each event to
+ * its source claim/remit/provider) arrives in Phase 4 once
+ * `provider_added` and `remit_received` events get their drawer
+ * surfaces; for now the events aren't drillable from this view —
+ * clicking them does nothing. The ProviderDrawer's Overview already
+ * surfaces the provider's `provider_added` event via the Dashboard
+ * activity feed (Task 2.5).
