Upgraded Angular and dependencies to v21, refactored DI to use inject(), and modernized Cypress config.

Changes:

• Bump all Angular and related packages to v21
• Replace constructor-based DI with inject() across all components and services

• Switch tsconfig.json to bundler module resolution
• Add provideZoneChangeDetection to main bootstrap
• Fix template syntax
