chore: remove dead code

Drops one module nothing loads and 53 exports nothing imports, found by
running the TypeScript language service over every exported declaration in
web/, electron/ and mobile/ and keeping only the symbols with zero
references outside their own file.

useRecentDocuments was stranded by 65dd652 (decommission the dashboard):
its only remaining consumer was its own test. LayerEffectType was never
referenced at all — the layer-effect union is built from the per-effect
interfaces directly.

The rest keep their code and lose the `export` keyword, so the modules
stop advertising an interface no caller uses.

electron and mobile came back clean: every candidate there is imported by
a test.
