Summary by CodeRabbit

• New Features
  • Added REST endpoints to create/update and delete Livechat custom fields, with input validation and clearer error responses. Returns the created/updated custom field. UI now uses the new save endpoint with a structured payload. Endpoints require authentication and Livechat Manager permission.
• Deprecations
  • The legacy method livechat:saveCustomField is deprecated. Use livechat/custom-fields.save instead; a deprecation warning is logged when the old method is called.
