Subject: [PATCH] fix(studio): hide shared pooler chart for high availability
 projects (#49904)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

High Availability projects run Multigres and don't have Supavisor, so
the Shared Pooler (Supavisor) client connections chart in the database
report only ever rendered an "Unable to load data" error for them. This
hides the chart for HA projects, following the same pattern as the Disk
IO Burst Balance chart.

**Changed:**
- `supavisor-connections-active` chart is now hidden when
`project.high_availability` is true

**Added:**
- Unit tests covering the shared pooler chart's visibility for standard,
HA, and unentitled projects

## To test

- Open Reports → Database on a High Availability project – the Shared
Pooler (Supavisor) client connections chart should no longer appear
- Open the same report on a standard Pro project – the chart should
still render as before

## Summary by CodeRabbit

* **Bug Fixes**
* The active connection chart is now hidden for High Availability
projects and projects without the database entitlement, preventing empty
or unavailable data from being displayed.

* **Tests**
* Added coverage to verify the chart appears only for eligible standard
projects.
