Implement sorting functionality for roadmap subtasks

Description

The current sorting functionality only allows for epics to be reordered using JQL, but subtasks remain unsortable. This limitation affects the organization and visibility of the subtasks within the roadmap.

Based on customer report it would enhance the user experience if subtasks were also made sortable.
