[PATCH manager v4 5/6] ui: sdn: remove IPv6 forwarding hint from fabric edit window

[Lukas Sichert <l.sichert@proxmox.com>]

The fabric edit window warned users to enable global IPv6 forwarding
when configuring an IPv6 fabric prefix. This is no longer required, as
the SDN backend now enables per-interface IPv6 forwarding where needed
via force_forwarding.

Remove the hint to avoid suggesting the broader host-wide sysctl
setting, which can disable Router Advertisements on the host.
