Generalize the outpost token-pinning path beyond the LDAP outpost so any
proxy outpost declaring a token authenticates against the authentik
server with the vault token instead of the blueprint's auto-generated
one. Drive both from a single rendered script over a target list.
Also raise the server healthcheck start_period to 120s: cold first boot
runs DB migrations plus app init (~90s observed), which tripped
compose --wait as unhealthy at the old 30s.
