Helper Tool 1.0.3

## Descriptions 
Some users reports that Proxyman doesn't revert back the original Proxy Setting before overriding. Therefore, they couldn't access the internet after quitting Proxyman.

We should fix it.

## 🤯 Changelogs 
- [x] Improve logic for Helper Tool -> Revert back to original Proxy Setting
- [x] Add macOS Proxy badge in bottom-left.
