Add task completion animations and fix 7-day task count

Animation Testing:
- Add AnimationTesting module with 14 animation types for task completion
- Include 4 celebration animations: Implode, Firework, Starburst, Ripple
- Card shrinks, shows checkmark with effect, then moves to next column
- Extended timing (2.2s) for celebration animations

Task Count Fix:
- Fix "7 Days" and "30 Days" counts on residence cards and dashboard
- Previously used API column membership (30-day "due soon" column)
- Now calculates actual days until due from task's effectiveDueDate
- Correctly counts tasks due within 7 days vs 8-30 days
