Fix Tor startup: remove false-positive port collision check

The defensive check `IsPortInUse(hiddenServicePort)` always fails
because port 24112 is the P2P port, which the node binds BEFORE
Tor starts. The check was incorrectly detecting our own listener
as a collision, causing "Tor failed to start" on every launch.

The hidden service is supposed to forward to 127.0.0.1:24112 where
the node is already listening — that's the correct state, not an error.
