// Package udp manages user-defined UDP integrations: inbound listeners
// (WSJT-X, JTDX, MSHV log events; JTAlert ADIF; N1MM XML; DXHunter call)
// and outbound emitters (db_updated → notifies Cloudlog/N1MM when HamLog
// just logged a QSO).
//
// One Server per connection row, started/stopped by the Manager when the
// user enables/disables or edits the row. Multicast support lets multiple
// apps share the same port without bind conflicts — essential since
// WSJT-X uses 2237 and several tools already listen there.
