📄 Description

Describe your changes

The health probe (IsHealthy) only checked the gRPC transport and a GetServerKey call. GetServerKey succeeds even when the peer cannot sync (e.g. the server returns "settings not found"), so the probe kept marking management Connected while the Sync stream failed in a tight retry loop — pinning the status to "Connected" forever despite no sync ever succeeding.

Track the last Sync stream error and have IsHealthy consult it, so a healthy transport is no longer enough to report the connection healthy.

Summary by CodeRabbit

Bug Fixes
- Improved management connection health reporting so sync streaming failures are no longer incorrectly treated as healthy.
- Health checks now more accurately reflect the combined connection status, preventing misleading “connected” indicators and ensuring disconnect handling triggers when sync streaming breaks.
