v1.0.7: Fix LocalTcpInterface mode — AP→GATEWAY to allow announce rebroadcasts

Browse Source 
MODE_ACCESS_POINT unconditionally blocks announce broadcasts in
Transport::outbound(), preventing local TCP clients from discovering
each other. Changing to MODE_GATEWAY allows announces to flow through
send_outgoing() which broadcasts to all connected clients.

Root cause: receiver's announce was stored in announce_table but never
rebroadcast on LocalTcpInterface, so sender could never find a path.
