feat(ui): simplify server panel — remove TLS/Discover, show full address in status

- Removed TLS checkbox (SSL still used internally, just not exposed in UI)
- Removed "Discover servers" button (discovery now runs automatically on panel open)
- ConnectionStatus now includes host:port when connected ("Connesso a ip:porta")
- Replaced status ellipse+text with a single TextBlock
