Backend: tor.list-services now hides services whose name maps to a
known-but-uninstalled catalog app (aliases covered: bitcoin/knots/core,
electrumx/electrs, btcpay, mempool). The node's own service, the relay,
and custom user services always show.
ISO: first-boot tor setup no longer pre-creates hidden services for six
apps that may never be installed — only the node's own onion is baked.
It also only seeds services.json/torrc on FIRST boot instead of
clobbering backend-managed services on every boot.
