make Pulse installation non-interactive (#4848)

* fix: streamline Pulse installation for web-based configuration

- Remove all interactive prompts during installation
- Remove .env setup (handled by web UI)
- Remove configuration messages (handled by web UI)
- Change install directory from /opt/pulse-proxmox to /opt/pulse
- Update JSON note to reflect web-based setup wizard

Pulse now features a complete web-based configuration system with
automatic setup detection, making manual .env configuration obsolete.

The new workflow:
1. Script installs Pulse without any user interaction
2. Service starts automatically
3. User navigates to the provided URL
4. Pulse shows setup wizard for configuration
5. No SSH or manual file editing required

This provides the ideal community script experience - completely
hands-off installation with configuration through the web interface.
