#738: Edit ▸ Paste pastes SVG markup as a shape layer

Problem: After Effects 26.3 pastes copied vector artwork as shape layers. Edit ▸ Paste only
knew the app's own clipboard, so SVG markup on the system clipboard was ignored; turning SVG
into shapes needed an imported footage file and Create Shapes from Vector Layer.

Fix: a new `edit.pasteSvg {svg, name?, comp?}` command builds a shape layer from SVG text with
the same conversion as Create Shapes from Vector Layer (paths, fills, strokes, gradients, clip
masks), above the selected layer with the SVG canvas centred in the comp, as one undo step;
oversized, non-SVG or shapeless text is rejected. In the UI, Ctrl/Cmd+V (and the native Edit ▸
Paste) run it when the system clipboard holds SVG. Copying in the app already replaces the
system clipboard with a note, so SVG there is newer than the app's clipboard.
