What does this implement/fix?

When a server keeps redialing, every unadmitted connection logs the same info line, so the daemon log fills with repeats of one event:

INFO:sendspin.daemon.daemon:Incoming connection did not complete admission (handshake timed out or was aborted); waiting for a retry.

I hit this watching my own player logs, where the line repeats on every reconnect and buries everything else. This keeps the first occurrence at info (an unadmitted connection would otherwise be fully silent, as the code comment notes) and moves repeats to debug. The flag resets once a connection is admitted, so a later wedged spell is visible again at info.

No behavior change apart from log level: three lines of state (one bool, set on first log, cleared on admission).
