* docs(enterprise): document programmatic library import/export API
- Add POST /import-libraries endpoint reference (openapi-enterprise.json + page)
- Register it under API Reference → Parse in the nav
- Add an Automating with the API section to the Library Import feature doc,
covering the cloud license-key export and the on-prem JSON import
* docs: update export endpoint to /api/v1/enterprise/export, plain language
Match the renamed cloud export path, move the license key into the request
body, and reword the automation section without em dashes.
* docs(enterprise): export uses Authorization header; import requires an API key
* docs(enterprise): document the force query param on import
