[STT-1622] Embargo and Schedule info lost when doing the "Copy and send to Desk" action

[BrianMwangi21]

Purpose

This PR ensures that embargo, publish_schedule, and schedule_settings fields are preserved when duplicating content to a desk in the "Send and Duplicate" flow. This is implemented via a client-side configuration flag that only affects the Send and Duplicate action, leaving regular duplication flows unchanged.

What has changed

• Modified DuplicateService.create_async() to conditionally preserve fields when the flag is set
• Added test scenario

Steps to test

1. Configure sendAndDuplicate.preserveEmbargoAndSchedule: true in superdesk.config.js like for STT
2. Create a story on any desk and add embargo and publishing schedule dates
3. Save the story
4. Click the "Send and Duplicate" button (sends to the configured target desk, e.g., Deski)
5. Verify the duplicated story in the target desk has the same:
   • Embargo date
   • Publishing schedule date
   • Schedule settings (timezone)
6. Verify the original story retains its embargo and schedule information
7. Test regular "Duplicate To" flow - fields should NOT be preserved

Note: This PR is related to this PR in superdesk-stt, and PR in superdesk-client-core

Resolves: STT-1622

Pull request overview

This PR addresses STT-1622 by allowing the archive duplication endpoint (used by “Send and Duplicate / Copy and send to Desk”) to optionally preserve scheduling-related fields that are normally stripped during duplication.

Changes:

• Added an optional request flag (preserve_embargo_and_schedule) to /archive/<guid>/duplicate to keep embargo, publish_schedule, and schedule_settings when duplicating to a desk.
• Updated the duplication service to pass extra_fields into archive_service.duplicate_content(...) when the flag is set.
• Added a feature scenario covering preservation behavior (currently only asserts embargo + publish_schedule).
