feat: add template and template group management via GraphQL

- Implemented GraphQL endpoints for importing, querying, and deleting Zabbix templates and template groups. - Added support for full template data import, including items, preprocessing steps, tags, and linked templates. - Implemented dependent item support by deferred creation logic in the template importer. - Added ability to query templates and template groups with name pattern filtering (supporting Zabbix wildcards). - Implemented batch deletion for templates and template groups by ID or name pattern. - Improved error reporting by including detailed Zabbix API error data in GraphQL responses. - Added comprehensive unit and integration tests covering all new functionality. - Provided GraphQL sample queries and mutations in the 'docs' directory for all new endpoints.
