feat(rule): add entryPath and sourceText fields to rule inputs

- Add entryPath field for ZIP entry path (e.g. 'folder/file.pdf')
- Add sourceText field for storing source excerpt/paragraph
- Add deleteByTypeAndFrom method to EdgeService/EdgeMapper
- RuleService.updateRule now handles inputs update
- Support precise source tracking for ZIP attachments
