Add automatic branch switching for updates

- Added branch detection and switching logic to both scripts
- manage-patchmon-dev.sh: automatically switches instances to dev branch
- manage-patchmon.sh: automatically switches instances to main branch
- Handles local changes by stashing before branch switch
- Creates local branch from origin if it doesn't exist locally
- Fixes issue where main branch instances couldn't be updated with dev script
