Remove duplicate checklists functionality

Checklists were duplicating subtasks functionality. Removed:
- Migration for task_checklists table
- TaskChecklistModel
- Checklist methods from TaskService
- Checklist routes from Routes.php
- Checklist controller methods
- Checklist UI section from show.twig
- Checklist JavaScript functions

Updated TASKS_MODULE_ROADMAP.md
