feat(chatwoot): comprehensive improvements to message handling, editing, deletion and i18n

- Fix bidirectional message deletion between Chatwoot and WhatsApp
- Support deletion of multiple attachments sent together
- Implement proper message editing with 'Edited Message:' prefix format
- Enable deletion of edited messages by updating chatwootMessageId
- Skip cache for deleted messages (messageStubType === 1) to prevent duplicates
- Fix i18n translation path detection for production environment
- Add automatic dev/prod path resolution for translation files
- Improve error handling and logging for message operations

Technical improvements:
- Changed Chatwoot deletion query from findFirst to findMany for multiple attachments
- Fixed instanceId override issue in message deletion payload
- Added retry logic with Prisma MessageUpdate validation
- Implemented cache bypass for revoked messages to ensure proper processing
- Enhanced i18n to detect dist/ folder in production vs src/ in development

Resolves issues with:
- Message deletion not working from Chatwoot to WhatsApp
- Multiple attachments causing incomplete deletion
- Edited messages showing raw i18n keys instead of translated text
- Cache collision preventing deletion of edited messages
- Production environment not loading translation files correctly

Note: Tested and validated with Chatwoot v4.1 in production environment
