Road to No Explicit Any Part 6: Composables and Extensions (#8083)

## Summary
- Type `onExecuted` callbacks with `NodeExecutionOutput` in saveMesh.ts
and uploadAudio.ts
- Type composable parameters and return values properly
(useLoad3dViewer, useImageMenuOptions, useJobMenu, useResultGallery,
useContextMenuTranslation)
- Type `taskRef` as `TaskItemImpl` with updated test mocks
- Fix error catch and index signature patterns without `any`
- Add `NodeOutputWith<T>` generic helper for typed access to passthrough
properties on `NodeExecutionOutput`

## Test plan
- [x] `pnpm typecheck` passes
- [x] `pnpm lint` passes
- [x] Unit tests pass for affected files
- [x] Sourcegraph checks confirm no external usage of modified types
