fix(web): Sidebar as client component (no DB during SSG)

- Sidebar.tsx is now "use client" — fetches /api/docs at runtime instead of
  calling listDocuments() during SSG (CI has no DB, causes ECONNREFUSED)
- GET /api/docs added to route.ts (returns doc list for sidebar)
- Removed SidebarContent.tsx (merged into Sidebar.tsx)
- Fixed isAuthorized double-brace typo
