Subject: [PATCH] Fix COB ladder bucket sizes: ETH uses  buckets, BTC uses 
 buckets

- Fixed hardcoded bucket_size = 10 in component_manager.py
- Now uses symbol-specific bucket sizes: ETH = , BTC =
- Matches the COB provider configuration and launch.json settings
- ETH/USDT will now show proper  price granularity in dashboard
- BTC/USDT continues to use  buckets as intended
