Implements the first temetro backend: an Express 5 API on Postgres via
Drizzle ORM, with authentication and multi-tenant clinics powered by
Better Auth.
- Auth: email/password with required email verification, password reset,
rate limiting, CSRF/trusted-origins, secure cookies, session audit hook.
- Organizations (clinics) with RBAC (owner/admin/member/viewer) and an
extended `patient` permission set; member invitations by email.
- Org-scoped patient records mirroring the frontend Patient shape, with
CRUD endpoints gated by permission (read/write/delete).
- Email helper logs links to the console when SMTP is unset (zero-setup
local dev); Dockerfile + docker-compose (db + backend + frontend) with
migrations applied on startup and a configurable Postgres host port.
