reachable_lan_address() parsed the launch port with url.rsplit(':')
which yields "8096/" for manifest interfaces.main URLs that carry a
path (http://localhost:8096/). That fails to parse and silently drops
a perfectly reachable launch URL, so apps like jellyfin, btcpay-server,
fedimint, gitea, nextcloud and portainer showed running with no launch
link in the UI. New launch_url_port() reads digits after the final
colon (mirroring port_from_url in the RPC layer) and tolerates a
trailing path. Adds regression tests.
