alex fe2d173b0f Optimize consolidation fetching with GROUP BY and reduced limit ...

Changed consolidation_group_limit from 100k to 10k for faster queries.

Reverted to GROUP BY approach for getting consolidation keys:
- Uses MySQL index efficiently: (UnitName, ToolNameID, NodeNum, EventDate, EventTime)
- GROUP BY with NodeNum ensures we don't lose any combinations
- Faster GROUP BY queries than large ORDER BY queries
- Smaller LIMIT = faster pagination

This matches the original optimization suggestion and should be faster.
