test: add unit tests for poultry repository and searchable dropdown functionalities

- Introduced tests for `PoultryScienceRepositoryImp` to validate delegated remote calls.
- Added comprehensive tests for `SearchableDropdownLogic` covering selection, overlay, and search logic.
- Enhanced `SearchableDropdown` widget tests for multi-select, label building, and overlay management.
