Run t3-dispatch as an unprivileged dedicated user instead of wizard (who has
full sudo). Privileged minting goes through /usr/local/bin/t3-mint, which
validates the target against /etc/ttyd-user-map before minting as that user;
sudoers permits t3-dispatch to run only that wrapper. Compromise of the
network-facing service can mint pairing tokens for mapped users at most.

Routes X-authentik-username -> per-user t3 instance; on no t3_session
cookie, mints a pairing token (as the OS user) and exchanges it at
/api/auth/bootstrap, injecting the session cookie. Listens :3780, reads
/etc/t3-serve/dispatch.json. Constants from the Task-1 auth-contract spike.
