docs: convert absolute documentation URLs to relative paths

- Replace 49 absolute https://docs.nextcloud.com/server/latest/ URLs with relative paths
- Improves documentation portability and offline validation
- Updates 36 RST files across user_manual, admin_manual, and developer_manual
- Maintains .html→.rst conversion and anchor links
- Preserves special URLs (OpenAPI, go.php, version 20)
