Create or update an env var scoped to a project. The project id comes from the path; the body still carries the scope/target, mirroring the settings-scoped POST (the FE sets `project_id` to the path id). Delegates to the same service as [`save_env_var`].

POST

/api/projects/{id}/env-vars

curl --request POST \
  --url https://example.com/api/projects/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/env-vars \
  --header 'Content-Type: application/json' \
  --cookie supacloud_session=<supacloud_session> \
  --data '{ "is_secret": true, "key": "example", "project_id": "2489E9AD-2EE2-8E00-8EC9-32D5F69181C0", "scope": "example", "value": "example", "workspace_id": "2489E9AD-2EE2-8E00-8EC9-32D5F69181C0" }'

Structured client error

Media typeapplication/json

The canonical JSON body of every error response — the single source of truth the frontend binds to. Every AppError serializes as this exact shape, and the generated OpenAPI component ApiErrorBody (with its ErrorCode enum) is what the frontend error schema is generated from, so there is no hand-written error schema on either end.
