## Problem
The "Healthy / Unhealthy" badge on the Observability overview was
alarming — showing **UNHEALTHY** even when every bar in the chart looked
fine. Two root causes:
1. **The threshold is aggressive.** Any period where the aggregate error
rate is ≥ 1% flips the badge to "Unhealthy", even if that 1% came from a
short burst that is visually indistinguishable in the chart.
2. **Period-wide aggregation hides spikes.** The badge status is
computed over the entire selected time window (e.g. 24 h). A 5-minute
spike at 20% errors diluted across 24 h of mostly-clean traffic can push
the aggregate just over 1%, triggering "Unhealthy" while all chart bars
look green.
The badge wording ("Unhealthy") also implies a current service problem,
whereas the underlying metric is a historical aggregate — making it easy
to misread.
## Change
Remove the badge entirely. The per-row error/warning rate indicator
(e.g. `● 1.34% errors`) already surfaces the key signal without the
alarming label, and the bar chart lets users see the actual shape of
traffic over time.
## On spike visibility in charts
The charts already use **COUNT per time bucket** (not averages), so
individual bars faithfully represent event volume. The bucket
granularity does compress spikes for longer windows (hourly buckets for
1–3 day views, daily for 7-day), but that's a separate concern from the
badge. If we want to surface burst detection in the future, a better
approach would be per-bucket threshold highlighting rather than a single
period-wide badge.

Table.
* **New Features**
* Replaced per-row bar charts with a line chart showing error/warning
rates alongside OK series.
* Added a centered "No data" placeholder when chart data is empty and
preserved click interactions on chart points.
