Chore: Typescript cleanup (1 / N) (#7817)

## Summary Remove 178 `@ts-expect-error` suppressions (935 → 757, 19% reduction) by fixing underlying type issues instead of suppressing errors. ## Changes - **What**: Type safety improvements across `src/lib/litegraph/` and related test files - Prefix unused callback parameters with `_` instead of suppressing - Use type intersections for mock methods on real objects - Use `Partial<T>` for incomplete test objects instead of `as unknown` - Add non-null assertions after `.toBeDefined()` checks in tests - Let TypeScript infer vitest fixture parameter types - **Breaking**: None ## Review Focus - `LGraphCanvas.ts` has the largest changes (232 lines) — all mechanical unused parameter fixes - Test files use type intersection pattern for mocks: `node as LGraphNode & { mockFn: ... }` - Removed dead code: `src/platform/cloud/onboarding/auth.ts` (47 lines, unused) ### Key Files | File | Change | |------|--------| | `LGraphCanvas.ts` | 57 suppressions removed (unused params) | | `subgraph/__fixtures__/*` | Fixture type improvements | | `*.test.ts` files | Mock typing with intersections | ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-7817-WIP-Chore-Typescript-cleanup-2da6d73d365081d1ade9e09a6c5bf935) by [Unito](https://www.unito.io) --------- Co-authored-by: Amp <amp@ampcode.com> Co-authored-by: GitHub Action <action@github.com>
