fix: Agent download endpoint and install script URL

- Move /get-agent route before auth groups to ensure it's public
- Fix path resolution in downloadAgent() - dirname(__DIR__, 2) from controller = /var/www/mon/
- Fix withStatus() return value issue in downloadAgent()
- Use /get-agent endpoint instead of /agent/agent.py (nginx issue with .py files)
- Update install.sh to use /get-agent URL
