xeno2426/webapp — reverse-engineered prompt

Build this existing web app into a clean, working version. There isn’t much documentation, so please inspect the code first and figure out what the current app is trying to do, then finish it without changing the basic idea. I want it to run locally without errors, show polished HTML pages, have sensible navigation, forms that actually submit, and clear success or error messages for normal users.

Please fix any broken backend behavior, database setup, and realtime push pieces that are already in the project. If the app is meant to use Postgres and deploy on Railway, make sure that path works too, including environment variables, migrations, static files, and a simple production start command. Keep the interface simple and usable, not overdesigned.

Clean up obvious bugs, remove dead code if it’s safe, and add a short README explaining how to install, run, migrate, and deploy it. Look up current docs online if you need to.
