feat(case): copy case timeline events to incident on escalation

[whitdog47]

This PR implements the automatic copying of timeline events from a case to a new incident when a case is escalated. This ensures that all relevant context and history from the case is preserved and visible in the incident’s timeline.

Details

• New Functionality:
  • When a case is escalated to an incident, all timeline events associated with the case are copied to the new incident.
  • The copied events retain their original details (description, timestamps, owner, etc.) and are marked as having been copied from the case.
• Integration:
  • The copying logic is integrated into the common_escalate_flow used during the escalation process.
• Testing:
  • Added a unit test to verify that case events are correctly copied to the incident and that the original case events remain unchanged.

• Consider adding assertions to verify that other event attributes (description, timestamps, owner, details) are copied correctly, not just the source, to ensure complete test coverage.

• Ensure that changes from copy_case_events_to_incident are committed to the database; if log_incident_event does not commit internally, consider calling db_session.commit() after copying.

• Consider wrapping the event-copying loop in a transaction or adding error handling to ensure atomicity and rollback on failure.
