Feature Request: Exclude/Ignore specific hosts from Proxmox Auto-Enrollment

Description

When using Proxmox Auto-Enrollment integration, PatchMon automatically discovers
all LXC containers and VMs from the Proxmox host, including those that cannot
run the PatchMon agent (e.g., Proxmox Backup Server).

After deleting such hosts from the inventory, they are automatically re-added
during the next discovery cycle.

Request

Please add the ability to exclude or ignore specific hosts (by VMID, hostname,
or IP) from the Proxmox Auto-Enrollment process. This could be:

• An exclude list in the Proxmox integration settings
• An "Ignore" button on the host detail page
• A filter option when configuring the enrollment token

Current Workaround

Manually deleting the host each time it reappears, which is not ideal.
