Subject: [PATCH] Refactor .NET installation logic in bootstrap script

- Changed the check for the existence of the .NET installation script to verify if the file exists instead of checking for execution permissions.
- Updated the command to run the .NET installation script from the repository root to ensure proper execution context.
- Added error handling to log a warning if the installation script fails and an error message if .NET is still not installed after the attempt, preventing SwarmUI from starting.
- Enhanced logging to confirm successful .NET installation, improving user feedback during the bootstrap process.
