## Summary
- Adds `leads:retry-failed-jobs` artisan command to selectively retry
failed `emails`-queue jobs after a Resend rate-limit incident
- Retries jobs for verified leads and `VerifyUserLeadEmailNotification`
for unverified leads; forgets jobs for deleted leads (DDoS cleanup) or
unverified leads receiving waitlist emails
- Adds `deleteWhenMissingModels = true` to all lead mail/notification
classes so future jobs for deleted leads are silently discarded instead
of failing
## Usage
```bash
# Preview (no changes)
php artisan leads:retry-failed-jobs --dry-run
# Execute
php artisan leads:retry-failed-jobs
```
## Test plan
- [x] `leads:retry-failed-jobs` forgets jobs for deleted leads
- [x] `leads:retry-failed-jobs` retries jobs for verified leads
- [x] `leads:retry-failed-jobs` forgets waitlist jobs for unverified
leads
- [x] `leads:retry-failed-jobs` retries
`VerifyUserLeadEmailNotification` for unverified leads
- [x] `leads:retry-failed-jobs` handles mixed job types correctly
- [x] `--dry-run` does not modify `failed_jobs`
## Summary
- gate waitlist signup behind email confirmation so only verified leads
receive a queue position and referral code
- add signed lead verification routes, a check-email page, and a
dedicated verification email for the waitlist flow
- update lead syncing and feature tests so only verified leads are
exported to Resend and referral movement happens after verification
