Add lesson complete button with homework-aware logic

- Show "Отметить как пройденный" button only on lessons without homework
- Show static "Пройдено" badge on homework lessons completed via approval
- Auto-create LessonProgress when curator/admin approves homework submission
- Revalidate student lesson, course, and dashboard pages on approval
