[WIP] Refactor everything server to be more modular and use recommended APIs.

* Updated architecture.md

* Refactor/renamed resources/dynamic.ts to resources/template.ts
  - refactor/renamed registerDynamicResources to registerResourceTemplates
    - this highlights the more salient fact that we are demonstrating registration of resource templates in this example.
  - exposed the ability to dynamically create the text resources from elsewhere (namely the resource-prompt example

* Added prompts/resource.ts
  - in registerEmbeddedResourcePrompt()
    - register a prompt that takes a resourceId and returns the prompt with the corresponding dynamically created resource embedded
