[pve-devel] [PATCH pve-manager] fix #5936: ui: backup: add CT PBS change detection mode selector

[Christian Ebner]

Allow to select the change detection mode when performing manual
backups of containers with Proxmox Backup Server as target, just like
for the advanced backup job options introduced by commit 3b21f19f
("www: advanced backup: add pbs change detection mode selector").

The selector is only shown in the backup window for containers and
only enabled when a Proxmox Backup Server is selected as target
storage.
