cproudlock 73438f593b Add smart refresh delay during carousel transitions ...

Prevents data refresh from interrupting carousel animations, especially
when looping from last event back to first.

Problem:
- Carousel rotates every 5 seconds
- Data refreshes every 10 seconds
- With 4 events: collision at 20s when looping back to index 0
- Refresh would cut off the smooth slide-up transition

Solution:
- Track transition state with isTransitioning flag
- If renderEvents() called during transition, store data and return early
- After 800ms transition completes, render pending data automatically
- Max delay: 800ms, only when collision occurs
- 99% of refreshes happen instantly (no collision)

Benefits:
- Works with ANY number of events (4 or 400)
- Smooth transitions every time
- Minimal delay (max 800ms, rarely happens)
- Future-proof - no magic timing numbers
- Console logs show when delay occurs

Timeline example (4 events):
- 0s: test 2 (index 0)
- 5s: test again (index 1) - transition starts, isTransitioning=true
- 5.8s: transition completes, isTransitioning=false
- 10s: REFRESH (no collision, renders immediately)
- 15s: test 3 (index 2)
- 20s: test (index 3) - transition starts
- 20s: REFRESH (collision! delayed)
- 20.8s: transition completes, pending data renders ✅
