Update jest-preset-angular to version 16.0.0

Objective

Update jest-preset-angular from version 14.6.2 to 16.0.0 to resolve compatibility issues with Angular 21 and improve test configuration.

Changes Made

1. Dependency Updates

• package.json: Updated jest-preset-angular from ^14.6.2 to ^16.0.0

2. Jest Configuration Migration

• jest.config.ts:
  • Migrated from deprecated globals configuration to the new transform syntax
  • Configured the transformer with necessary ts-jest options
  • Commented out globalSetup (optional and was causing compatibility issues)

3. TypeScript Configuration for Tests

• tsconfig.spec.json and projects/lux/tsconfig.spec.json:
  • Added emitDecoratorMetadata: true to properly support dependency injection in tests
  • Added paths mappings to correctly resolve Angular testing modules:
    • @angular/core/testing
    • @angular/common/http
    • @angular/common/http/testing
    • @angular/router/testing
    • @angular/platform-browser/animations

Issues Resolved

• ✅ Removed deprecation warnings about using globals in ts-jest configuration
• ✅ Fixed Angular testing module resolution errors (Cannot find module '@angular/core/testing')
• ✅ Improved compatibility with Angular 21 and Jest 30.2.0
• ✅ All tests now run successfully

Test Results

Test Suites: 14 passed, 14 total
Tests:       1 skipped, 109 passed, 110 total
Snapshots:   0 total
Time:        ~22-26s

Modified Files

• package.json - Dependency update
• jest.config.ts - Migration to new transform syntax
• tsconfig.spec.json - Added emitDecoratorMetadata and paths
• projects/lux/tsconfig.spec.json - Added emitDecoratorMetadata

Additional Notes

• The globalSetup configuration was commented out as it's optional and was causing compatibility issues. If needed in the future, it can be properly configured according to jest-preset-angular 16.x documentation
• The paths mappings in tsconfig.spec.json point directly to Angular type definition files to correctly resolve modules during TypeScript compilation in tests
