fix: omit unused components import in api-schemas.ts when no schemas found

[zedrdave]

Summary

When an OpenAPI spec has no schemas, api-schemas.ts was generated with:

import type { components } from './openapi-types.js'

// No schemas found in the OpenAPI specification

The components import is unused in this case, triggering a lint warning in consumer projects.

Fix

Remove the import type { components } line from the no-schemas early-return path in generateApiSchemasContent.
