Add Boys/beetroot color, bump event font size by 1px

- New 'Boys' member with beetroot color (#6B1040 / #D4A8C0) — any event
  containing the word "Boys" gets this color
- Mom/Dad were already matched via fuzzy alias detection (no change needed)
- Event card font sizes increased by 1px (12.5px body, 11.5px time, 11px member)
