[Server] Turn into executable

[jonnyhyman]

macOS:

• move all sudo commands to subprocess calls, which ask for sudo password each time, OR:
• capture computer password at startup, hold throughout, use echo "password" | sudo -S ... to run commands as sudo automatically. but then we're holding computer passwords in memory. dodgy?

Windows:

• require uac-admin on startup (doable with pyinstaller)
• test that all privileges are actually given

Starting with macOS...

The sudo required operations are:

• Restart PostgreSQL Server
• All Wireguard commands wg up, wg down
• Wireguard firewall config commands using pctl

It looks like the elevate package will do everything we need for every platform.
