fix: modal dialogs not receiving mouse clicks on Wayland 

frame_buf_at() could not find WINGs dialog frame_bufs because they
have no tree wrapper (only a bare scene_buf in WL_LAYER_FLOATING).
After the walk-up stops at the level_tree bucket, Step 4 only checks
fb->tree, missing tree-less frame_bufs entirely.

Add Step 5: match tree-less frame_bufs whose scene_buf node is a
direct child of a level_tree bucket. This resolves clicks on WINGs
modal dialogs (Run dialog, info panels, etc.).
