Polish UI components and rework AgentConfigForm

Major AgentConfigForm rework with improved adapter configuration
fields and layout. Refine sidebar, breadcrumbs, and card/tab
components for visual consistency. Clean up page layouts across
Activity, Agents, Approvals, Costs, Dashboard, Goals, Inbox,
Issues, Org, and Projects pages. Minor heartbeat-run CLI fix.
