feat(orchestrator): radio icon in the header opens the radio spot on every tab

The header radio button opens the radio spot above the main area of the current tab. The Send button, the toolbar radio button and the Radio tab are gone, the mayday clears inside the spot without a Cancel mayday label, and the radio station probe waits for a visible row.

+- [ ] The header shows Radio, Commands and Settings as icon buttons; Radio

+- [ ] No Radio tab, no "Send …" button and no radio button in the Agents
