chore: add MCP integration and refactor documentation into modular how-to guides

- Moved GraphQL query samples into a new `docs/queries` directory for better organization.
- Added new queries and mutations, including `createHost.graphql` and `GetApiVersion.graphql`.
- Introduced `mcp-config.yaml` and updated `docker-compose.yml` for MCP integration.
- Updated IntelliJ `.idea/workspace.xml` settings to reflect project changes.
- Added new how-to guides (`docs/howtos`) for permissions, tags, MCP integration, and schema usage.
- Enhanced tests by updating file paths and improving sample data locations.
- Refined permissions and host group structures in `zabbix-hostgroups.ts` and `resolvers.ts`.
