fix: remove dead code (toast stubs, unused Redis key, tunnel manager fields)

- Remove 7 no-op exported stubs from toast.tsx (ToastProvider, ToastViewport,
  Toast, ToastTitle, ToastDescription, ToastClose, useToasts) — nothing imports them
- Remove fwFailKey variable and its Set() call from worker.go — the
  firmware:check-failed Redis key was never read anywhere
- Remove unused deviceStore and credCache fields from tunnel.Manager struct
  and drop corresponding parameters from NewManager(); update call site in
  main.go and all test usages
