Console: NWC chatter behind a debug switch; dead relays remembered longer and dropped from the pool.

`coinosDebug(true)` in the console (or ?debug=1) turns the nwc: listener
logs back on; they are off by default. Warnings and errors stay.

The red WebSocket lines were the pool's own reconnect loop redialling relays
from other people's relay lists that have been dead for weeks — the sick
list only stopped NEW dials, for ten minutes, and forgot on reload. A dead
relay is now dropped from the pool (no reconnect loop), skipped twice as
long each time it fails (up to a day), keyed by normalized URL, and the
verdict survives a reload. A relay the pool has failed to reconnect to
three times counts as dead.
