fix(KB-186): add ID-based tiebreaker to sort comparators for stable ordering

Browse Source 
- Add numeric ID tiebreaker to TaskStore.listTasks() when createdAt timestamps match
- Add same tiebreaker to InlineCreateCard and TaskDetailModal dependency dropdown sorts
- Add store-sort integration test verifying ascending ID order with identical timestamps
- Add InlineCreateCard tests for identical-timestamp dropdown ordering and search filtering
- Add TaskDetailModal test for identical-timestamp dependency dropdown ordering
