feat(05-03): extend document detail page with PreparePanel

- Fetch allClients in parallel with doc via Promise.all
- Import PreparePanel and render in 1/3 right column of 2/3 + 1/3 grid
- currentClientId defaults to doc.assignedClientId ?? doc.clientId
- asc import added from drizzle-orm for ordered client list
- npm run build is clean with no TypeScript errors
