Adds a full admin view (users + projects, with view/delete) gated
server-side by ADMIN_EMAIL in server/auth.js (defaults to the site
owner's account, overridable via env var for other deployments). The
gate is enforced on every /api/admin/* route, not just hidden in the
UI — verified a non-admin session gets 403 even when it hits the
endpoints directly. Deleting a user leaves their projects in place
(not cascade-deleted) so admin cleanup can't accidentally destroy
someone's study data.

Projects were previously global to anyone who could reach the server.
Adds email/password accounts with httpOnly cookie sessions, scopes
every project (both SQLite and localStorage) to the signed-in user,
and auto-claims pre-existing unowned projects for whoever registers
first. Also adds optional TOTP two-factor auth with backup codes,
managed from a new Account Settings page, since there's no
password-reset flow to fall back on otherwise.
