ScubeScripts/sc_phonetax ? reverse-engineered prompt

Build me a simple FiveM phone tax resource called sc_phonetax.

I want it to work with both ESX Legacy and QBCore, and I want the whole thing to be easy to configure from a config file. The script should check players for one or more phone items, since some servers use different phone items, and charge them a phone tax based on the settings. If a player cannot pay, it should handle that cleanly with a clear notification.

Please include support for a custom notification system, but also let me use the normal ESX or QBCore notifications if I prefer. Keep the code clean and efficient, and make it simple to drop into a server and start using right away. If you need to look up current framework docs online, go ahead and do that.
