Invalid `date` query parameter on email failures endpoint fails with 500

[innokenty]

Description

Calling GET /api/admin/email-failures with a malformed date query parameter results in a 500 Internal Server Error.

Steps to Reproduce

Anything that isn't a proper yyyy-MM-dd date breaks the same way:

• GET /api/admin/email-failures?date=invalid-date
• GET /api/admin/email-failures?date=2026/01/12
• GET /api/admin/email-failures?date=2026-01-12T00:00:00Z

All return: 500 Internal Server Error
Expected: 400 Bad Request
