Chore/type hints and examples

[NEFORCEO]

🚀 Description

OAuth2 examples

Added examples/oauth2/ directory with two examples: client_credentials.py (basic usage) and shared_auth.py (reusing auth across routes).

Type hints

• OAuth2Scope — new Literal type alias for OAuth2 scope autocompletion in editors
• startup_uuid_version: str → Literal["v4", "v7"]
• HTTPMethod — reused instead of inline Literal in _add_route
• params/json: dict → dict[str, Any] (app.py + session.py)
• dependencies: list → list[Any] (app.py)
• method in session.py: str → HTTPMethod (request + stream)
• headers/req_headers: dict → dict[str, str]
• query/req_json: dict → dict[str, Any]
• request_configs (client.py): dict → dict[str, dict[str, Any]]
• Fixed typos: Primutive → Primitive, RequestsOptinal → RequestsOptional
