## Summary
- Adds `leads:resend-verification-emails` artisan command that
dispatches `VerifyUserLeadEmailNotification` to all leads where
`email_verified_at IS NULL`
- Supports `--dry-run` flag to preview the count without sending
- Follows the same pattern as `leads:retry-failed-jobs` (progress bar,
summary table)
## Test plan
- [ ] `--dry-run` shows correct count without dispatching
- [ ] Command dispatches exactly one notification per unverified lead
- [ ] Verified leads are skipped
- [ ] Early exit when no unverified leads exist
