feat: implement weather sensor extension and enhance device interfaces

This change introduces the Weather Sensor device type which retrieves data from public APIs, and enhances the core Host/Device interfaces to provide consistent access to inventory and items across all specialized device types. It also improves search logic and fixes several bugs identified during implementation.

- Weather Sensor Extension: Added schema and recipe for a device retrieving weather data via Zabbix HTTP agent items.

- Interface Enhancements: Added inventory and items fields to Host and Device interfaces to ensure all device specialized types have consistent access to monitoring and inventory data.

- Search Logic Improvements: Enhanced ParsedArgs to support searchByAny and technical name (host) searches when a name pattern is provided.

- Bug Fixes:

  - Fixed getLocations argument order in the Zabbix API datasource.

  - Implemented deduplication for groupids and templateids in HostImporter to prevent Zabbix duplicate value errors.

  - Added missing url field to CreateTemplateItem for HTTP Agent item support.

- Testing:

  - Extended the regression test suite with 4 new automated checks covering the fixed bugs.

  - Updated Jest tests to accommodate the improved search parameters.

- Documentation: Updated cookbook and test specifications to reflect new features and regression testing obligations.
