Add display_metrics setting per server

- Add display_metrics JSON field to servers table
- Update server edit form with metric checkboxes
- ServerDetailController now uses server's display_metrics setting
- If no metrics selected - show all (backward compatibility)
- Removed hardcoded metric names from queries
