Road to No explicit any: Group 8 (part 8) test files (#8496)

## Summary

This PR removes unsafe type assertions ("as unknown as Type") from test
files and improves type safety across the codebase.

### Key Changes

#### Type Safety Improvements
- Removed improper `as unknown as Type` patterns from test files in
Group 8 part 8
- Replaced with proper TypeScript patterns using Pinia store testing
patterns
- Fixed parameter shadowing issue in typeGuardUtil.test.ts (constructor
→ nodeConstructor)
- Fixed stale mock values in useConflictDetection.test.ts using getter
functions
- Refactored useManagerState tests to follow proper Pinia store testing
patterns with createTestingPinia

### Files Changed

Test files (Group 8 part 8 - utils and manager composables):
- src/utils/typeGuardUtil.test.ts - Fixed parameter shadowing
- src/utils/graphTraversalUtil.test.ts - Removed unsafe type assertions
- src/utils/litegraphUtil.test.ts - Improved type handling
- src/workbench/extensions/manager/composables/useManagerState.test.ts -
Complete rewrite using Pinia testing patterns
-
src/workbench/extensions/manager/composables/useConflictDetection.test.ts
- Fixed stale mock values with getters
- src/workbench/extensions/manager/composables/useManagerQueue.test.ts -
Type safety improvements
-
src/workbench/extensions/manager/composables/nodePack/useMissingNodes.test.ts
- Removed unsafe casts
-
src/workbench/extensions/manager/composables/nodePack/usePacksSelection.test.ts
- Type improvements
-
src/workbench/extensions/manager/composables/nodePack/usePacksStatus.test.ts
- Type improvements
- src/workbench/extensions/manager/utils/versionUtil.test.ts - Type
safety fixes

Source files (minor type fixes):
- src/utils/fuseUtil.ts - Type improvements
- src/utils/linkFixer.ts - Type safety fixes
- src/utils/syncUtil.ts - Type improvements
-
src/workbench/extensions/manager/composables/nodePack/useWorkflowPacks.ts
- Type fix
-
src/workbench/extensions/manager/composables/useConflictAcknowledgment.ts
- Type fix

### Testing
- All TypeScript type checking passes (`pnpm typecheck`)
- All affected test files pass (`pnpm test:unit`)
- Linting passes without errors (`pnpm lint`)
- Code formatting applied (`pnpm format`)

Part of the "Road to No Explicit Any" initiative, cleaning up type
casting issues from branch `fix/remove-any-types-part8`.
