Color-code events by family member name anywhere in title

- Fuzzy name matching: if a member's name appears anywhere in the event
  title (word boundary, case-insensitive), it gets their color — no
  [prefix] required. e.g. "Daniel's Week" → green, "Jason Karate" → blue
- More vibrant card color palette (deeper pastels, stronger border accent)
- Bolder event title text and slightly thicker left border for clarity
