The bulk search service now returns empty response DTOs instead of
throwing RuntimeException when no results are found. Updated tests
to use assertFalse(hasAnyResults()) instead of catching exceptions.
Adds the ability to apply provider search results to parts directly
from the bulk import step 2 page without navigating to individual
part edit forms. Includes per-result Quick Apply buttons and an
Apply All button for batch operations.
- Add BulkSearchResponseDTO, FieldMappingDTO for type safety
- Use composition instead of inheritance in BulkSearchResultDTO
