feat(zero): admin UI for Zero notes management

Adds new admin section 'Заметки Зеро' (☕) with:
  - manual 'Generate' button with channel/bucket/allow-dup form
  - status filter tabs with counters (draft/approved/published/failed/skipped)
  - per-note actions: approve / edit inline / regenerate with bucket pick / skip
  - status-colored cards with bucket icon, pose, scheduled time MSK
  - error display with attempt counter
  - tokens & model footer
