Upgrade Angular to latest version (v20.2.3)

[Copilot]

This PR upgrades the Angular framework from version 19.2.5 to the latest version 20.2.3, providing access to the newest features, security updates, and performance improvements.

Changes Made

Framework Upgrades

• Angular Core: 19.2.5 → 20.2.3
• Angular CLI: 19.2.6 → 20.2.1
• Angular DevKit Build: 19.2.6 → 20.2.1
• All Angular packages (@angular/common, @angular/forms, @angular/router, etc.) updated to 20.2.3

Configuration Updates

• Updated TypeScript configuration with moduleResolution: "bundler" for improved compatibility
• Angular CLI workspace configuration updated to maintain previous style guide behavior
• Minor dependency updates (TypeScript 5.8.3, Zone.js 0.15.0)

Migration Process

The upgrade was performed using Angular's official migration tool (ng update) which automatically handled:

• Package version updates
• Configuration file migrations
• Compatibility adjustments
• Breaking change detection and fixes

Verification

✅ Build Status: Application builds successfully with no errors
✅ Test Suite: All 4 existing tests continue to pass
✅ Development Server: Runs correctly on localhost:4200
✅ UI Functionality: All existing features and styling preserved
✅ Compatibility: Standalone components and modern Angular patterns work seamlessly

Benefits

• Access to latest Angular 20 features and APIs
• Improved performance and bundle optimization
• Enhanced security with latest patches
• Better developer experience with updated tooling
• Future-proofing for continued Angular ecosystem support

The application maintains full backward compatibility with no breaking changes required in the existing codebase. All themes, Bootstrap integration, and custom styling continue to function as expected.
