fix: seat limit + suspend guard per Codex; harden factory email uniqueness

- seat limit follows the active/cancelling package, not a newer inactive record
- suspend/reactivate toggle refuses closed accounts (terminal); closed shown in list
- factory emails use a large unique numeric space (safeEmail pool could collide
  late in a full suite run)
