Parent: #2
Depends on: #9, #10, #13, #14

Scope

Add preset, grid, concentric, fCoSE, ELK, and Dagre layout invocation behind the graph adapter.
Respect pinned nodes and commit final positions as one transaction.
Persist viewport, stylesheet choice, filters, hidden groups, and optional selection.
Add named saved graph views that reference the same canonical graph.
Restore graph state after refresh without an automatic destructive relayout.

Acceptance criteria

Saved positions and viewport reopen exactly.
Layout completion is undoable as one transaction.
Pinned nodes remain fixed.
Saved views do not duplicate graph data.
Refresh restores the current graph and active saved view.
