Bonsai: skip out-of-view-layer spaces in toggle_hide_spaces (#5309)

Toggling space visibility crashed with
`RuntimeError: Object 'IfcSpace/...' cannot be hidden because it is not in
View Layer 'ViewLayer'!` when a space object lived in a collection excluded
from the active view layer. tool.Spatial.toggle_hide_spaces called
hide_get/hide_set unconditionally; Blender raises for any object not in the
active view layer. The rest of spatial.py already guards these calls via
view_layer.objects.get(obj.name); this method was the outlier.

Filter the spaces to objects present in the active view layer, derive the
toggle direction from the first surviving object, and apply hide_set only
to those. Objects not in the view layer are skipped (they cannot be hidden
anyway). Also returns cleanly when nothing is toggleable.

Verified live in headless Blender: with one space in an excluded
collection, the old code raised the reported RuntimeError; the fix
completes, hides the in-view-layer space, and skips the excluded one. Core
test_spatial.py: 12 passed.
