Add comprehensive tests for filtering and import/export functionality
- Created `test_filters.py` to test the EntryFilter and FilterOptions classes, covering default values, custom values, filtering by status, DNS type, resolution status, and search functionality. - Implemented tests for combined filters and edge cases in filtering. - Added `test_import_export.py` to test the ImportExportService class, including exporting to hosts, JSON, and CSV formats, as well as importing from these formats. - Included tests for handling invalid formats, missing required columns, and warnings during import. - Updated `uv.lock` to include `pytest-asyncio` as a dependency for asynchronous testing.
