fix(web): unbreak kg-web tsc build for v0.12.0 release

Three type-only fixes blocking `tsc -b` (no runtime change, emitted JS
is identical — these only satisfy the type checker):

- BlockPalette: PaletteBlock.icon typed React.ElementType -> LucideIcon.
  React 19's @types/react resolves className to `never` on the wide
  ElementType union; every palette icon is a lucide icon anyway, so the
  precise type is also the correct one.

- ForceGraph types: EngineNode.source / EngineEdge.source typed
  APIGraphNode / APIGraphLink -> RawGraphNode / RawGraphLink. These now
  match what transformForEngine actually receives — the store's
  canonical raw-graph format (ontology optional), not the REST payload.

- useFitCamera / useOrientAndFrame: parametrize three.js's now-generic
  EventDispatcher as EventDispatcher<{ start: object }> so
  addEventListener('start') is not rejected against the empty default
  event map ({} -> keyof {} -> never).

Tag v0.12.0 moved forward to this commit so the release tag points at a
commit where the full image set builds.
