gsxdsm 1b7bb1fe18 FN-7639: wire message editing into Planner Chat

Adds the ability to edit and resend a prior user message in task-detail Planner Chat, discarding subsequent turns without reverting already-applied steering/refinement side effects.

- Wire FN-7628's editChatMessage + rewindSessionForEdit into TaskPlannerChatTab for synthetic task-planner:<id> sessions
- Add edit affordance/UI flow and message resend handling in TaskPlannerChatTab
- Ensure already-applied steering comments and refinement tasks are not reverted when a turn is discarded
- Expand TaskPlannerChatTab test coverage for edit/resend flows
- Update dashboard guide docs to describe the new Planner Chat edit behavior
- Add changeset for @runfusion/fusion (minor)
