This commit introduces a first-pass /login/ endpoint with a Bootstrap-backed HTML form for collecting username and password, while also renaming the existing @auth.verify_password callback from login to auth_verify_password. The rename prevents the auth function from colliding with the new Flask route handler and makes the authentication flow easier to reason about as the app grows. The page is mostly a UI scaffold for now rather than a complete login workflow, but it establishes the entry point for browser-based authentication.
