Build me a Fish Vendor POS web app for fish vendors, with a clean browser based interface and a Rust backend. I want admins, shop managers, and cashiers to be able to sign in, with proper role checks, active account checks, and password resets. The app should let staff manage products, categories, inventory, and product images, then run checkout with accurate pricing, stock updates, and rollback if a sale fails. Include barcode support for common codes, printable labels, sales history, dashboard metrics, charts, CSV export, and PDF reports. Keep the data in MariaDB, make it work with Docker Compose, and serve it securely through HTTPS with a local development setup too. Please also include the original browser app assets if needed, plus a simple health check endpoint and a way to manage the initial admin account from environment variables. If you need current docs for Rust libraries or deployment details, look them up online.
