applets/taskmanager: Consolidate Meta+1–9 shortcuts into Backend

Move the Meta+1–9 shortcut registration into Backend::setupShortcuts(),
alongside the cycling and move shortcuts added in d29361ea.

The dispatch now uses the same priority order as the other task
shortcuts, preferring a non-screen-filtered taskbar with the active task,
then a screen-filtered one, with a last fallback that lets Meta+number
launch pinned apps even when no task is active.

Shortcut action IDs are preserved ("activate task manager entry 1"
through "10"), so existing user customizations in kglobalshortcutsrc
continue to work.

Part of the decoupling from shellcorona described in the companion MR:
plasma-workspace!6848.
