fix: eliminate jam "no output" state + restructure header UI (#963)
backend: add fallback output on disconnect (prefers host), broaden
auto-output to any connecting client, not just host.
frontend: split jam header into two rows (identity+actions / output+mode),
remove "no output" UI branch, add defensive mobile overflow CSS.
