Pull request overview

This PR extends the login flow to support authentication with either a username or an email address, replacing the previous username-only login. A new get_user_by_identifier service function performs an OR-based lookup, the LoginRequest schema is updated to accept either field, and the client UI and generated API types are updated accordingly.

Changes:

• New LoginRequest schema accepts either username or email (with a model-validator enforcing at least one) and exposes a computed identifier property
• New get_user_by_identifier DB query replaces get_user_by_username in the authentication path; authenticate_user and login service signatures renamed username → identifier
• Client Login.tsx unified the form input into a single "Username or Email" field; generated TypeScript types and Zod schemas updated to match
