Keep rejected plan content visible in plan mode

When a plan is rejected, preserve and display the plan content so users
can still see what was proposed. The rejection message is now shown in
yellow (AccentYellow) instead of green to visually indicate the rejected
state.

Changes:
- Add 'rejected' flag to PlanResultDisplay interface
- Update PlanSummaryDisplay to conditionally color message based on rejection
- Preserve plan content in coreToolScheduler when plan is cancelled
- Add tests for both rejected and approved plan rendering
