Road to No explicit any: Group 8 (part 7) test files (#8459)

## 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 17 test files in
Group 8 part 7
- Replaced with proper TypeScript patterns using factory functions and
Mock types
- Fixed createTestingPinia usage in test files (was incorrectly using
createPinia)
- Fixed vi.hoisted pattern for mockSetDirty in viewport tests  
- Fixed vi.doMock lint issues with vi.mock and vi.hoisted pattern
- Retained necessary `as unknown as` casts only for complex mock objects
where direct type assertions would fail

### Files Changed

Test files (Group 8 part 7 - services, stores, utils):
- src/services/nodeOrganizationService.test.ts
- src/services/providers/algoliaSearchProvider.test.ts
- src/services/providers/registrySearchProvider.test.ts
- src/stores/comfyRegistryStore.test.ts
- src/stores/domWidgetStore.test.ts
- src/stores/executionStore.test.ts
- src/stores/firebaseAuthStore.test.ts
- src/stores/modelToNodeStore.test.ts
- src/stores/queueStore.test.ts
- src/stores/subgraphNavigationStore.test.ts
- src/stores/subgraphNavigationStore.viewport.test.ts
- src/stores/subgraphStore.test.ts
- src/stores/systemStatsStore.test.ts
- src/stores/workspace/nodeHelpStore.test.ts
- src/utils/colorUtil.test.ts
- src/utils/executableGroupNodeChildDTO.test.ts

Source files:
- src/stores/modelStore.ts - Improved type handling

### 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`.
