Fix: Add exponential backoff to compute reconnection attempts 
When a remote compute is unreachable, the controller now uses exponential
backoff for reconnection attempts: 5s, 10s, 20s, 40s, 80s, then caps at
300s (5 minutes). Previously it retried every 5 seconds indefinitely.

User-initiated operations (open project, start node) still trigger an
immediate connection attempt, so recovery is not delayed in practice.

Fix: Check compute connection status before project deletion 
This commit addresses issue #2703 where deleting a project with nodes
on remote compute nodes would result in long waits with no feedback
if those computes were unreachable.

Changes:
1. Compute connection status updates on connection failure
   - When a compute fails to connect, update connected=False and last_error
   - Send compute.updated notification to UI so users can see status
   - This allows Web UI to display real-time connection status

2. Project deletion checks compute status before attempting deletion
   - Check all computes used by the project are connected
   - If any compute is disconnected, immediately reject deletion
   - Provide clear error message indicating which computes are offline
   - This prevents long timeouts and gives users immediate feedback

Benefits:
- Immediate feedback instead of 120-second timeouts
- Clear error messages about which computes are disconnected
- Prevents orphaned resources on offline computes
- Improves user experience by avoiding silent waits

Update compute.py 
Remove check for open project. Without this check a remote can be rebooted and will be usable once the main server polls it again. Without this the main server would need to open a project that already uses the remote server or restart the main server's gns3 process.
