Ensures session bus socket and kwalletd5/6 talk permissions are set at
logon, so Flatseal or a missing manifest entry cannot silently break
Talk's credential storage and Plasma integration.

--scope ... & had two problems:
1. systemd-run stayed alive in the autostart service cgroup;
KillMode=control-group sent it SIGTERM when logon_script.sh exited,
tearing down the scope and killing Talk mid-initialization.
2. The scope lacked Delegate=yes, preventing Electron's zygote from
creating sub-cgroups for the GPU/renderer processes.
The previous commit added Delegate=yes but kept --scope, so problem 1
remained: the scope was still torn down on service exit, causing the
GPU/network service crash visible in talk.log.
Switch to a transient service unit identical to the Nextcloud Desktop
Client fix: --no-block returns immediately so systemd-run is gone from
the cgroup before the service ends; --property=Delegate=yes is retained
for Electron's zygote. Tested: service active, zygote and network
service running, no GPU crash.

Nextcloud Talk is an Electron app. Electron uses a zygote process to
fork sandboxed child processes (GPU, renderer, network service) into
their own sub-cgroups. systemd-run --scope without Delegate=yes locks
down the cgroup — sub-cgroups cannot be created — so the zygote fails,
causing the GPU process to crash immediately on startup.
Adding --property=Delegate=yes hands cgroup management to the scope,
allowing flatpak/bubblewrap and Electron's zygote to create the
sub-cgroups they need. Tested: no GPU crash with this flag set.

setsid -f forks the process into a new session but leaves it in the
calling service's cgroup. systemd-run --user --scope moves it into its
own transient scope cgroup so the autostart service can finish normally.
Added & to background the launch, replacing the fork that setsid -f
was providing. Tested: scope is created and Talk starts correctly.
