Build me a simple Telegram bot in Python that has a clean menu, button based navigation, and callback handling for interactions.

I want it to be easy to run locally or in Docker, with the main bot logic separated from the button layouts, callback handlers, constants, and shared helper functions so the code stays organized. It should use a token from environment variables or a simple config setup, and include a few basic starter screens or actions so I can extend it later.

Please set it up in a way that feels like a reusable bot template, not a one off script. If anything in the current Python Telegram docs has changed, look it up online and use the current approach.

Also make sure the project has clear entry point code, sensible defaults, and enough structure that I can add new commands and callback buttons without rewriting everything.
