refactor!: rewrite as dependency and add security info to OpenAPI schema

[disrupted]

close #162

BREAKING CHANGE: rewrite middleware as FastAPI dependency

Middleware is always a global handler on app-level. Authentication should use the dependency pattern which allows more granularity. Therefore the exclude parameter is no longer needed. FastAPI infers the security information for the OpenAPI schema from the SecurityScheme Model which is returned by the dependency.

Usage

jwks_auth = JWKSAuth(jwks_validator=...)

# global: protect all endpoints
app = FastAPI(dependencies=[Security(jwks_auth)])

# specific API router
app.include_router(APIRouter(dependencies=[Security(jwks_auth)]))

# specific route
@app.get("/test")
def get_test_route(credentials: Annotated[JWKSAuthCredentials[FakeToken], Security(jwks_auth)]):
    ...
