Fix Simple Mapping not applying during sync - preserve id field

Root cause: The UUID (id) field was being stripped when saving path mapping:
- Backend ReplacementRule model was missing id field
- Frontend pathMappingToApi() didn't include id in conversion
- Backend update_path_mapping endpoint didn't save id

Changes:
- Add id field to ReplacementRule model in main.py
- Include id when saving path mapping rules in update_path_mapping
- Include id in frontend pathMappingToApi conversion
