Unify task stats calculation and update UI labels

- Create shared TaskStatsCalculator for consistent date bucket logic
- Fix widget stats to use exclusive buckets (overdue | 7 days | 30 days)
- Update labels: "This Week" → "Next 7 Days" / "7 Days"
- Large widget now shows Overdue, 7 Days, 30 Days (removed Total)
- Rename "Pros" tab to "Contractors"
- Remove red pulsing ring from residence card icons
