Tasks: single-occurrence recurrence + Today/Tomorrow/Next 7/Later + icons

Switch lists from calendar-expansion (every occurrence in every section)
to the TickTick model: one task contributes ONE next-active occurrence.

- VM: nextActiveOccurrence + activeRows; replace todayTasks/next3/upcoming
  with todayTasks/tomorrowTasks/next7DaysTasks/laterTasks buckets. A
  recurring task shows a single row; completing it advances to the next.
- TodayView: sections are now Today / Tomorrow / Next 7 Days / Later
  (UpcomingSection gained a title param).
- TaskRowView: add ⏰ (reminder) and 🔁 (recurring) indicators on the right;
  fix the hardcoded "Annual" label to show the real frequency.

Calendar grid keeps per-date occurrences (it's a date grid, not a list).
Matrix dynamic promotion (Problem 4) handled separately.
