Batch commit of the property-panel work: multi-fill Fill editor, stroke
edit modes (uniform/per-side), clip support, plus polish — every
property-panel icon centred in its hover wash (fill X, padding/stroke
gears, gradient/effect remove), justify-row + size washes fit-content,
stroke duplicate width removed (inline width Single-only, per-side grid
otherwise), Openverse register link fixed + hover, ImageSrc Arc bump.
Known issue: stroke-width edit does not persist on a node whose
node_stroke_slot is None (see cmd_set_node_stroke_width) — follow-up.
