Surface refused relay publishes; publish NWC info once per session

relay.coinos.io's write policy was rejecting every 23195/13194 hal sent
(kinds were whitelisted to coinos server pubkeys — incompatible with
hal's per-connection service keys) and the rejections temp-banned the
IP. publishOn swallowed all of it, which disguised a relay-side policy
problem as a client bug. The relay policy is fixed separately; here,
refused publishes now log the relay and reason, and the 13194 info
event goes out once per connection per session instead of on every
listen() so replies keep their share of the relay's per-IP rate budget.
