fix(openapi): remove schema-level examples from error schemas to fix codegen

datamodel-codegen interprets schema-level `example` values as type constraints,
creating numbered classes (Error1, Error2, Type1, etc.) instead of reusing the
shared ErrorDetail type. Remove examples from error schemas so all error
responses use ErrorDetail directly, producing clean class names.

Also add title: ErrorDetail to the inline error object in ErrorResponse.yaml
so datamodel-codegen generates a named class instead of a numbered one.
