feat(telegram): add business owner configuration and message handling

- Introduced `business_owner` field in Telegram settings to specify the owner ID.
- Updated `handleBusinessMessage` to ignore messages from the business owner.
- Added tests to verify that messages from the owner are correctly ignored.
- Enhanced Telegram form to include input for business owner ID.
- Updated localization files for English, Portuguese, and Chinese to include business owner labels.
