Lyra v0.4.7 — CW decoder UX + TCI JTDX audio fix

Connect — wrong/stale IP self-heal (#183)

Lyra now probes the remembered radio IP before connecting and, if the radio isn't at that address (DHCP lease changed, moved subnets, powered off), scans and connects to it at its current address instead of opening a dead IP. Fixes a report of Lyra launching connected to the wrong IP with a frozen window.
