fix: normalize default feedback date range

The initial feedback range should match setDateRange's startOfDay/endOfDay normalization. Otherwise the first "Last 30 days" window can exclude part of the boundary days until the picker changes.

Keep the serialized useState initializer inline because this is a small JSON-safe default shape, not a reusable behavior.
