fix: tandoor listens on unix socket by default — bind gunicorn to TCP 8080

The vabene1111/recipes 2.x image starts gunicorn on unix:/tmp/tandoor.sock
unless TANDOOR_PORT is set, so Traefik got 502. Set TANDOOR_PORT=8080 and
point the domain to 8080 (80 was never listening).

Deploy-tested on a Dokploy instance: HTTP 200, setup page renders.
