Sidebar: use item label for tooltip, show id when debugging

[ronso0]

Currently the tooltips are the item Ids, and the "Quick Links" string (??)

Showing playlist name #tracks, duration exactly like in the sidebar may seem redundant but it can be helpful if the sidebar is too narrow to show for long names

If this is not welcome, let's show nothing, only ids for debugging with --develper.

btw, Windows builds fail with

Rebase on 2.3?

[ronso0]

I consider it a UX inconvenience/inconsistency not really a bug.
but, sure why not..

Thank you! LGTM

This created a merge conflict with main. @ronso0 or @uklotzde could you please resolve that?

[ronso0]

it's just the change from if else to the switch cases. not complicated, I noticed when rebasing.
I can fix that earliest tomorrow night, like in a day

[uklotzde]

Merged into main.
