feat(deps): adds support for Angular 19 and migrates the component to a fully standalone structure (#45)

BREAKING CHANGE:
YES

## Description

This pull request modernizes the `@sourceloop/search-client` library and
its example by upgrading to Angular 19, refactoring the search component

maintainability.
