[Bug]: Actions Ring opens under panels/docks on Linux Wayland, and off-cursor on multi-monitor

Summary

On Linux under a Wayland compositor (reproduced on KDE Plasma/KWin), the Actions Ring can open hidden behind a desktop panel or dock, and its position is unreliable on a multi-monitor setup — it can open on the wrong monitor entirely, or offset from the actual cursor position.

Root cause

• Panel occlusion: the overlay opens the ring as a plain WindowKind::PopUp, which on Wayland is just another xdg_toplevel surface. Nothing about that guarantees it draws above a panel/dock's own always-on-top surface (typically a zwlr_layer_shell_v1 overlay-layer surface, which genuinely is guaranteed to be on top). A panel can legitimately draw over the ring.
• Wrong/stale position: openlogi_hook::cursor_position() on Linux queries X11's query_pointer via XWayland. Under a native Wayland session this isn't a real Wayland pointer query and doesn't track the actual pointer — it reports a stale, display-ambiguous coordinate (confirmed live: identical coordinates returned across multiple cursor moves and clicks on different monitors).

Steps to reproduce

1. Run OpenLogi on Linux under a Wayland session (e.g. KDE Plasma/KWin) with a visible panel/dock.
2. Bind a button to ShowActionsRing.
3. Press it while the cursor is under/near the panel, or on a secondary monitor.
4. Observe: the ring can render behind the panel, and/or appear on the wrong monitor or away from the actual cursor position.

Environment

• KDE Plasma (KWin), Wayland session, multi-monitor (primary + secondary at a nonzero global X offset).
