OpenAPI schema

The client-side app needs up to date schemas. If you change something in the API, then you need to upgrade the schema as well. Run: docker compose run --rm api funkwhale-manage spectacular > ./api/funkwhale_api/common/schema.yml.

Then you need to regenerate the app schema has well by running yarn generate-types-from-local-schema.

Be aware that get_signup_form_additional_fields_serializer can tweak the schema generation.
