fix: alignment, section order, and tooltip duplication

- Move symbol badge inline with input (flex items-end) so symbol and
  rack inputs align at the bottom
- Move Signal Timeline chart above Slot Evidence table
- Deduplicate signal fires by slotId per day in chart data processing
  and by slotName in tooltip rendering (prevents MACD Bullish etc
  from appearing twice)
