yiekheng a5bbf3a25d feat(bot): redesign reminder time picker (menu-driven)
Time picker UX changes after live testing:
- Add "🕐 Now" quick option (fires within 30s)
- Remove "🕐 In 1 hour" / "🕒 In 3 hours" — Now + Tomorrow 9 AM cover the
  practical fast-path
- Replace free-text custom date input with a 3-step menu picker:
  Day (Today, Tomorrow, +2d, +3d, +4d, +5d, +1w, +2w, +1m)
  → Hour (24-hour grid, daytime first)
  → Minute (5-min increments)
- Validate the chosen day+hour+minute against "now" and reject if past

Drops parseFreeText path entirely; the wizard's set_time step is gone.
