Alexander Brown 43f0ac2e8f 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 |
