feat(onboarding): auto-create a default workspace at signup

- CreateUser now provisions a default "{name}'s Workspace" for non-invite
  signups (email, Google, GitHub, seeder), with the owner as Admin and
  current_workspace_id set. Invite signups still skip it (they join the
  inviter's workspace on acceptance).
- UserSeeder drops its now-redundant explicit CreateWorkspace call.
- After Stripe checkout, billing/processing lands the user on the social
  accounts screen with the connect dialog open (was: calendar), so onboarding
  flows straight into connecting an account.

Quantity stays correct (1 workspace → checkout quantity 1). The first workspace
is created without brand details; brand setup remains available in Settings and
on the create-workspace screen for additional workspaces.
