Delete an information request for an audit

Deletes an information request for an audit. This performs a soft delete, marking the request as deleted (setting deletionDate) while preserving it in the system for audit history and compliance tracking.

Soft deletion allows:

• Maintaining complete audit trail of all requests ever created
• Retrieving deleted requests via changedSinceDate for synchronization

After deletion:

• The request will not appear in normal list responses (without changedSinceDate)
• The request's deletionDate field will be populated
