• fix(calendar): make batched multi-event approvals stop re-prompting and not partially apply (#1450)

calendar_update_event and calendar_delete_event now use a coarse approval resource ("update event" / "delete event") so "always allow" persists across a batch and one approval covers a multi-event reschedule, matching calendar_create_event. Ambiguous filler replies during an approval (e.g. "lol") re-prompt for a clear yes/no instead of interrupting the batch and leaving it partially applied.

Fixes #1449.
