Support for project ontology change

[lb-pno]

Description

Elevenlabs requested this change. It reverts a restriction so users can change a project's ontology.

Changes

• The MediaType of an ontology is now accessible: Ontology.media_type

Example

Common

def simple_ontology():
    classifications = [
        {
            "name": "test_ontology",
            "instructions": "Which class is this?",
            "type": "radio",
            "options": [
                {"value": c, "label": c} for c in ["one", "two", "three"]
            ],
            "required": True,
        }
    ]

    return {"tools": [], "classifications": classifications}

1. Working case - same media type for project and ontology

# Create a project with Image media type
project = client.create_project(
    name="my_image_project",
    media_type=MediaType.Image
)

# Create and connect first ontology
first_ontology = client.create_ontology(
    "first_ontology",
    simple_ontology(),
    media_type=MediaType.Image
)
project.connect_ontology(first_ontology)

# Create and connect second ontology with same media type
second_ontology = client.create_ontology(
    "second_ontology",
    simple_ontology(),
    media_type=MediaType.Image
)
project.connect_ontology(second_ontology)  # This works because media types match

1. Working case - media type unknown for the ontology

# Create a project with Image media type
project = client.create_project(
    name="my_image_project",
    media_type=MediaType.Image
)

# Create and connect first ontology
first_ontology = client.create_ontology(
    "first_ontology",
    simple_ontology(),
    media_type=MediaType.Image
)
project.connect_ontology(first_ontology)

# Create and connect second ontology with same media type
second_ontology = client.create_ontology(
    "second_ontology",
    simple_ontology()
)
project.connect_ontology(second_ontology)  # This works because media types match

2. Non-working case - different media type for project and ontology

# Create a project with Image media type
project = client.create_project(
    name="my_image_project",
    media_type=MediaType.Image
)

# Create and connect first ontology
first_ontology = client.create_ontology(
    "first_ontology",
    simple_ontology(),
    media_type=MediaType.Image
)
project.connect_ontology(first_ontology)

# Create and connect second ontology with different media type
second_ontology = client.create_ontology(
    "second_ontology",
    simple_ontology(),
    media_type=MediaType.Video
)
project.connect_ontology(second_ontology)  # ValueError: Ontology and project must share the same type, unless the ontology has no type
