Add organization onboarding wizard in console

[gearnode]

Summary

Adds an unlisted organization onboarding wizard at /organizations/:organizationId/onboarding for peer / new org setup.

• Steps: SCIM → access review connectors → Probo agent → MCP instructions → congrats
• UX: Learn panel (copy + animated SVG illustrations), Do panel (embedded existing flows), Do this later on each integration step
• Persistence: Integration “done” comes from GraphQL; deferrals are session-only (in-memory context, no backend / no localStorage)
• Entry: Redirect after Create organization to ?welcome=1; same URL is shareable (not linked from nav)
• Layout: hideSidebar focused layout; employees and auditors are redirected away
• Spec: contrib/claude/onboarding.md

Test plan

• Create a new organization → lands on onboarding step 1 (SCIM)
• Connect SCIM (IdP or manual) → Continue enables; stepper shows complete
• Do this later advances without marking complete; congrats lists pending items
• Add access review source; register a device; MCP step Continue → congrats
• Open /organizations/:id/onboarding directly when integrations already done → congrats
• Employee role cannot access wizard (redirect to employee portal)
