feat: add age-based event gating, event timer, and UI polish

- Add minAge/maxAge to events so infants can't go treasure hunting
- Cache event panel DOM to prevent high-speed button destruction
- Add 10s auto-select countdown for choice events
- Fix event title/text field mapping (name/description → title/text)
- Add rotating clock icon for time flow feedback
- Fix speed/pause button active states
- Fix shop affordability check (disable + show insufficient money)
- Add red styling for unmet choice requirements
- Fix log re-rendering on every tick
