Add actionable push notifications and fix recurring task completion

Features:
- Add task action buttons to push notifications (complete, view, cancel, etc.)
- Add button types logic for different task states (overdue, in_progress, etc.)
- Implement Chain of Responsibility pattern for task categorization
- Add comprehensive kanban categorization documentation

Fixes:
- Reset recurring task status to Pending after completion so tasks appear
  in correct kanban column (was staying in "In Progress")
- Fix PostgreSQL EXTRACT function error in overdue notifications query
- Update seed data to properly set next_due_date for recurring tasks

Admin:
- Add tasks list to residence detail page
- Fix task edit page to properly handle all fields
