Block unsupported hosts before enabling terminal.send.

v2Host.list and mobile host selection check only host access and online status. They do not enforce host-service version 1.22.0. An older host cannot serve terminal.send, so submission fails at runtime.

Disable quick keys while terminal.send is in progress.

Line 100 keeps QuickKeysRow enabled while Line 101 only passes isSubmitting to GlassComposer. WorkspaceScreen.handleQuickKey sends raw bytes through TerminalWebView.sendInput, so it bypasses host terminal.send serialization. Since the host sends text and Enter separately, a quick key can arrive between them and alter the submitted terminal action. Pass isSubmitting to QuickKeysRow and disable its buttons until onSubmit settles.
