Fix: Show UTC+1 time on chart and fix indicator redrawing

Changes:
1. UTC+1 Time Display
   - Updated formatDate() to add 1 hour offset for Central European Time (UTC+1)
   - Added timeFormatter to chart timeScale for x-axis labels
   - Both signal display and chart time axis now show UTC+1 time

2. Fix Indicator Redrawing
   - Added missing getActiveIndicators() call in drawIndicatorsOnChart
   - Fixed variable scope issue where activeIndicators wasn't defined
   - Ensures indicators are properly removed and recreated when new candles close
