Subject: [PATCH] USER-WP-0039: show the account-site session's assurance
 beside its uid (NK-WP-0051-T03)

The account-site line shows its KeyCape token's aal1/aal2. Authelia's own
authentication_level is not shown: KeyCape checks the one-time code, so
Authelia reports level 1 even for an aal2 sign-in.
