DaTina6996/mecanica ? reverse-engineered prompt

Build me a Lua based mechanic resource for a game server called mecanica. I want players to be able to work as a mechanic, repair damaged vehicles, fix engine and body problems, and handle simple payments or billing when the job is done. If it makes sense, include a small menu or interaction flow so a player can start a repair, see what it costs, and finish it without a lot of fuss. Keep it clean and easy to configure so I can change prices, job access, and basic settings later.

Please set it up in a way that feels ready to drop into a server, with sensible defaults and clear code comments where needed. If you need to check current docs or best practices for the game framework, look them up online and use whatever is most standard.
