fix: resolve PVE backup visibility issue with hybrid node discovery and filtering fixes

Implements comprehensive solution for GitHub issue #80 where PVE backups stored on local node storage weren't appearing in the backup tab. Adds intelligent node discovery system that creates direct connections to access node-local storage while maintaining backward compatibility with shared storage setups.

Key improvements:
- Hybrid discovery approach with automatic node IP detection and connection caching
- Fixed data structure mismatches and key collision issues for duplicate VMIDs across nodes
- Corrected PVE backup filtering logic in summary cards and calendar views
- Enhanced API token permission documentation for storage content access
- Optimized connection handling with reduced timeouts for faster discovery cycles

+    - This applies even for read-only access to backup listings

 ### Common Issues

+*   **Empty Backups Tab:** 
+    - **PBS backups not showing:** Usually caused by missing `PBS Node Name` in the settings configuration. SSH to your PBS server and run `hostname` to find the correct value.
+    - **PVE backups not showing:** Ensure your API token has `PVEDatastoreAdmin` role on `/storage` to view backup files. See the permissions section above.
 *   **Pulse Application Logs:** Check container logs (`docker logs pulse_monitor`) or service logs (`sudo journalctl -u pulse-monitor.service -f`) for errors (401 Unauthorized, 403 Forbidden, connection refused, timeout).
 *   **Configuration Issues:** Use the settings modal to verify all connection details. Test connections with the built-in connectivity tester before saving. Ensure no placeholder values remain.
 *   **Network Connectivity:** Can the machine running Pulse reach the PVE/PBS hostnames/IPs and ports (usually 8006 for PVE, 8007 for PBS)? Check firewalls.
