nakflix/NakflixPlus — reverse-engineered prompt

Build me a Telegram file sharing bot like a polished file sender that I can deploy on Heroku or a VPS. I want it to let me store posts or files from a database channel and generate shareable links for users. It should support batch sharing too, so one link can open more than one post or file.

Please make it easy to customize, especially the welcome message and the force subscribe flow. I want force subscribe to work with both a channel and a group, and the subscribe buttons should be flexible so I can use 1, 2, or 3 buttons depending on what I set in the config. The bot should be able to check that users joined before giving access.

Please wire up the basic database side, the bot commands, and a clean config with environment variables so setup is straightforward. Also add simple deployment instructions and make sure it works when the bot is added as admin in the required channels and groups. If anything is unclear, look up current Telegram bot docs online.
