fix: glitchtip errors (locale, email) + E2E submission cleanup

- Add fallback 'de' locale to toLocaleDateString() to prevent RangeError
- Skip sending emails for submissions from 'testing@mintel.me'
- Update check-forms.ts to automatically delete test submissions via Payload API
- (Manual) Configured MAIL_FROM and MAIL_RECIPIENTS on alpha.mintel.me
