Replace the misleading "Step 1/Step 2" wizard pattern with a cleaner
dashboard-style layout. This better reflects the actual user flow of
selecting and configuring integrations.
Changes:
- Remove AgentStepSection wrapper and numbered badges
- Replace with standard SectionHeader for consistent typography
- Wrap PVE/PBS/PMG tables in Card components for better visual hierarchy
- Group action buttons (Discovery, Refresh, Add Node) in card headers
- Enhance empty states with icons and better messaging
- Fix spacing between integration selector and configuration sections
- Remove unused AgentStepSection import
All agent types (PVE, PBS, PMG, Docker, Host) now have consistent
presentation and improved visual clarity.
