Improve ImunifyAV installation with better progress display

Changes:
- Show 'please wait' message for long installation
- Display installation progress from deployment script
- Clean up any existing deployment script first
- Show relevant output: Installing/Installed/Complete/Error
- Remove suppression of all output

This should make ImunifyAV installation more visible and debuggable.
