fix(routing): rename main service app->pds so caddy resolves THIS stack on shared proxy

The caddy sidecar uses on-demand TLS and asks http://app:3000/tls-check before issuing a cert. On a
multi-tenant host every co-located stack aliases its main service 'app' on the shared 'proxy' overlay;
caddy (on proxy+internal) resolves bare 'app' to a FOREIGN stack's endpoint, the tls-check is refused,
no cert is issued, and HTTPS is dead (xrpc/_health=000). Renaming the service to 'pds' gives a unique
swarm DNS name that only this stack publishes, so caddy's reverse_proxy/on_demand_tls always resolve
this PDS. (A network alias would be cleaner but abra drops compose network aliases on deploy; the
service name is always applied.)
