fix: cockpit/flowpilot bugs and redesign view toggle placement

- Fix return type annotation on unified_chat_service.send_chat_message (6→7 tuple)
- Fix stale closure in CockpitPage handleStepComplete auto-advance logic
- Fix IncidentHeader copy link hardcoding /assistant/ path (now uses current URL)
- Wire psaTicketId from session data through to CockpitPage incident header
- Fix FlowPilotAsks showing only first question — add chevron navigation for all
- Redesign ViewToggle: add icons (MessageSquare/LayoutDashboard) and subtitles
- Move view toggle from chatbar toolbar to standalone row above input on dashboard
- Standardize toggle placement across dashboard, FlowPilot, and Cockpit pages
