🟡 Medium · Daytime metrics get overnight advice

When an empty hrr or nap_min history is opened, kDaytimeMetricKeys omits both keys, so MetricDetail selects metricDetailWearBandFix and tells users to wear the band overnight even though these metrics come from daytime bouts or sleep outside the main night.

Add hrr and nap_min to kDaytimeMetricKeys.

Also at test/metric_detail_empty_hint_test.dart:27, lib/ui2/screens/metric_detail.dart:69.

Include resting-HR guidance for these metrics.

If a new user has no measured, manual or historical resting HR, daytime wear alone cannot produce calories, strain or TRIMP. Add guidance to wear the band overnight or enter resting HR manually, as well as wearing it during the day.

🟡 Medium · Steps regression goes unnoticed

When a daytime key such as steps is accidentally removed from kDaytimeMetricKeys, when kDaytimeMetricKeys omits steps, the loop at line 27 of metric_detail_empty_hint_test.dart stops creating the Steps case, so Steps can show the overnight hint while every remaining assertion passes.

Use an independent explicit list of expected daytime keys in the test, so omissions from the production set fail coverage.
