fix(kanban): remove orphan conflict markers from kanban.py (#28459)

PR #28454 (salvage of #26745, workflow filter) merged with leftover
git conflict markers in hermes_cli/kanban.py at three sites:
- _task_to_dict() (session_id alongside workflow_template_id/current_step_key)
- p_list parser (--sort alongside --workflow-template-id/--step-key)
- _cmd_list (order_by alongside the new filter kwargs)

Cleans up the markers and keeps both halves at each site.

Resolves a self-introduced regression.
