carsten 5be79a7c7a Add simple JWT login for User
Password hashing via pwdlib (argon2id), stateless JWT auth (2h expiry)
delivered as an Authorization: Bearer token, with an OAuth2PasswordBearer
dependency (app/dependencies.py) protecting future routes. Establishes
app/routers/ as the convention for feature routes, explicitly registered
in main.py (no auto-discovery, unlike app/models/).

The first admin user is seeded via an Alembic data migration gated on
SUPERUSER_EMAIL/SUPERUSER_PASSWORD env vars (read at migration-run time
only, never persisted to .env/git) rather than a script or open endpoint,
so a fresh `alembic upgrade head` still succeeds without them. The
migration mirrors the users/organization tables locally instead of
importing the live SQLModel classes, keeping it a stable schema
snapshot; it does import app.core.security.hash_password, a pure
utility with no table-shape dependency.
