Onboarding page, team_token migration, and embedded demo video

[bbeatricecretu]

Summary

• New dashboard Onboarding page and a restructured team-knowledge detail panel (apps/dashboard/src/app/onboarding/page.tsx, onboarding-view.tsx, wiki-tree.tsx).
• DB migration: switch from team_id (UUID) to team_token (text) as the team key, with corresponding API, MCP server, schema, seed, and shared-types updates.
• Landing page Demo section now embeds the live YouTube walkthrough (kD6nnJAmRK8) instead of the "coming soon" placeholder.

Test plan

• apps/dashboard builds; visit /onboarding and confirm the new page renders.
• Run the 2026-04-26-token-as-team-key.sql migration on a scratch DB; verify API endpoints still resolve teams via team_token.
• Re-seed via packages/db/seed.mjs and confirm MCP server (apps/mcp-server) authenticates with token.
• Open apps/landing-page/index.html (served over HTTP) and confirm the Demo section plays the YouTube embed.
