✨ Node previews for project homepage

[pcrespov]

What do these changes do?

Creates an API to get node's preview files (i.e. pairs thumnails+file url). Current implementation produces fake screenshots (see how to test)

• ✨ extends webserver API 0.21.0 → 0.22.0. See openapi.json specs
  • GET projects/{project_id}/nodes/{node_id}/preview to get a node's preview
  • GET projects/{project_id}/nodes/-/preview to get a list of all results above . i.e. for all node_ids in the project
  • NOTE: with WEBSERVER_DEV_FEATURES_ENABLED=1 it will return fake homepage info
• ♻️ error handling and used helper function for envelope_response

Related issue/s

• resolves API: get screenshots per node for project #4370
• @GitHK follows up this issue and connects with storage backend
• Found some issues with images mimetypes.guess_type works differently in webserver's image #4385

How to test

Manual tests:

• Start stack with WEBSERVER_DEV_FEATURES_ENABLED=1
• Create a project w/ nodes
  • Have at least one dynamic service
  • Drop e.g. this glb file and name the file-picker such that it includes the word fake in the label. Them it will be presented as a fake screenshot file_url
• In swagger, just GET projects/*/nodes/*/preview and GET projects/*/nodes/-/preview

very nice, please consider my comments.

GET projects/*/preview

For the project wide call, instead of providing a flat list, could you please provide one flat list per node?

👍 merci
