Subject: [PATCH] Fix scheduledAt type in SendEmailTaskInput and add Date
 normalization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Update SendEmailTaskInput.scheduledAt to support string | Date types
- Add Date object normalization to ISO strings in sendEmail processing
- Ensure consistent database storage format for all timestamp fields
- Convert Date objects to ISO strings before database operations

Resolves remaining "Type Date is not assignable to type string" error
for scheduledAt field in job task input.
