feat: Rework Monaco editor integration

Until now, we were importing Monaco directly which massively increased our bundle size. By moving to
 ngx-monaco-editor-v2, Monaco is loaded on-demand. Also add support for monaco-yaml, which provides
 Intellisense for our yaml configs using OpenAPI schemas. This is also our first component using
 signals.

 Closes #2089
