[Copilot]

This PR upgrades the Angular framework from version 19.2.5 to the latest stable version 20.3.1, along with all related dependencies and necessary compatibility fixes.

What was upgraded

Core Angular packages:

• Angular framework: 19.2.5 → 20.3.1
• Angular CLI: 19.2.6 → 20.3.2
• Angular DevKit Build Angular: 19.2.6 → 20.3.2

Related dependencies:

• RxJS: 6.6.7 → 7.8.2 (major version upgrade for better performance)
• ngx-bootstrap: 19.0.2 → 20.0.2 (updated for Angular 20 compatibility)

Technical fixes applied

TypeScript compatibility:

• Updated TypeScript lib configuration from ES2018 to ES2020 to support PromiseSettledResult type required by Angular 20
• Updated moduleResolution to bundler in TypeScript configuration

API migrations:

• Replaced deprecated TestBed.get() calls with TestBed.inject() in test files
• Fixed RxJS Subject typing for void subjects to work with RxJS v7 stricter typing requirements

Automatic migrations:

• Applied Angular CLI automatic migrations for workspace configuration
• Updated build system defaults to maintain compatibility

Testing

• ✅ All 13 existing tests pass
• ✅ Build process works without errors
• ✅ No breaking changes to application functionality
• ⚠️ Some deprecation warnings from external dependencies (bootstrap, fontawesome) remain but don't affect functionality

Benefits

This upgrade brings:

• Performance improvements from the latest Angular version
• Enhanced developer experience with better tooling
• Security updates and bug fixes
• Future compatibility with modern web standards
• Access to latest Angular features and optimizations

The upgrade maintains full backward compatibility while providing access to the latest Angular ecosystem improvements.
