fix: 4 bugs from regression testing

- BUG-1: Strip HTML tags in sanitizeName (prevent stored XSS)
- BUG-2: Strip HTML tags in notes via sanitizeText across all 3 booking APIs
- BUG-3: Dashboard excludes archived/past MCs and expired Open Day events from counts
- BUG-4: Truncate long names in booking cards to prevent overflow
