feat(vitest-angular): add UI and coverage options to test

[jorgeandrespadilla]

PR Checklist

Closes #1520

What is the new behavior?

This PR adds support for the --coverage and --ui flags in the @analogjs/vitest-angular builder CLI. Users can now dynamically enable these options without manually configuring them in angular.json.

Example usage:

ng test --coverage   # Display test coverage  
ng test --ui         # Enable UI mode  

This simplifies testing workflows by reducing unnecessary angular.json complexity.

Does this PR introduce a breaking change?

• Yes
• No
