passbolt: fix login behind Traefik (TLS termination, GPG fingerprint)

Traefik terminates TLS and forwards HTTP, so PASSBOLT_SSL_FORCE=false (in-container redirect caused an infinite loop); Service/Ingress on port 80; add HTTP->HTTPS redirect middleware at Traefik instead. Set PASSBOLT_GPG_SERVER_KEY_FINGERPRINT to the migrated server key (1471F6B1...) so the GPG login handshake completes.
