[cuegui] UI stops updating due to gRPC connection drops ("Connection reset by peer")

[ramonfigueiredo]

Describe the bug
CueGUI (Cuetopia/CueCommander) intermittently stops updating the UI. When this occurs:

• Double-clicking a job in the Monitor Jobs panel does not populate the details/frames section
• Job status remains stale (e.g., shows "In Progress" when jobs have actually finished or failed)
• The "autoload mine" feature stops working reliably
• The only workaround is to close and reopen the application

The following errors appear in the terminal:

WARNING   FrameMonitorTree gRPC connection interrupted during frame update, will retry
WARNING   FrameMonitorTree rpcObjects is None
grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with:
    status = StatusCode.UNAVAILABLE
    details = "recvmsg:Connection reset by peer"

To Reproduce
Steps to reproduce the behavior:

1. Launch CueGUI (Cuetopia or CueCommander)
2. Set up a filter to monitor jobs (e.g., filter by show/department regex)
3. Use the application for an extended period (30+ minutes to several hours)
4. Double-click a job in the Monitor Jobs panel
5. Observe that the details/frames section remains blank or shows stale data
6. Check terminal output for "gRPC connection interrupted" and "Connection reset by peer" errors

Expected behavior

• Double-clicking a job should immediately display its layers and frames in the details section
• Job status should update in real time as frames complete or fail
• The UI should remain responsive and accurate throughout the session without requiring a restart
