Replaces the stateless signed-cookie session (bare user_id) with a
real server-side sessions table -- the cookie now just carries an
opaque session id, resolved against the DB on every request. Each
session records IP address (respects X-Forwarded-For), a parsed
device label, and last-seen time (throttled updates, not written on
every request).
New GET/DELETE /api/auth/sessions endpoints and an "Active sessions"
section in Profile settings let a user see every device they're
logged in from and revoke one they don't recognize -- including their
own current session, which just signs them out.

Site admins can invite a brand-new person by email from the Admin portal
Users tab -- a signup-link email lets them set their own username/password
and lands them in the app already logged in. Existing users invited to a
room now also get an email. Closes the "invited but never notified" gap
from both directions.
SMTP is configured through the Admin Settings tab at runtime (not the env
file), persisted in a new smtp_settings table with the password encrypted
at rest via a Fernet key derived from SESSION_SECRET -- the first
reversible secret this app stores in the database. A "send test email"
button surfaces real delivery errors; the invite/notification paths
themselves never fail loudly, since an SMTP outage shouldn't block an
action that already succeeded in the database.
New site_invites table mirrors RoomInvite's shape but targets an email
address with no room context; the raw signup token is hashed the same way
API tokens are, and only ever exists in the email link. POST /api/signup
is the first genuinely public, unauthenticated account-creation endpoint
in this app, reusing the existing register_user path for identical
validation.
