cosmic-app-list: Launched apps are put in a wrongly-named cgroup #960
Description
When launching an app from the bottom panel, the name of the cgroup the app is launched in is incorrect, it is named /app-cosmic-com.system76.CosmicAppList-<number>.scope instead of using the app name/ID.

When launching from the search, the assigned cgroup name is as expected (app-cosmic-com.system76.CosmicEdit-<number>.scope in this case):

Tested in a VM using the latest COSMIC alpha ISO (pop-os_24.04_amd64_intel_17.iso).
Why this matters
Proper cgroup assignment is important for modern system monitoring utilities (e.g. Mission Center) to be able to differentiate running applications from system processes. See https://gitlab.com/mission-center-devs/mission-center/-/issues/231 for info on which DEs currently handle this.
