feat(ui): mobile polish — tab bar icons, server overlay, status text

Tab bar: replace plain Header strings with icon+label StackPanels
(≡ ↑ ↓ ⊙ ⊕); style TabStrip with UniformGrid so all five tabs share
the full width equally; center content and add touch padding. Icons
are visible only on mobile (IsMobile binding); desktop keeps text only.

Server settings overlay: dual layout for host/port/TLS input (vertical
on mobile: host full-width, port+TLS side by side) and for action
buttons (stacked full-width on mobile). Known-server list item shows
host on one line and tcp/ssl ports on the line below on mobile.

Connection status bar: simplify to "connesso" / "non connesso" —
remove the "a host:port" suffix from the connected state and
consolidate all disconnected/error/cert-changed states to conn.none.
