Remove dead code: unused MetricSummary fields and calculateMin/calculateMax functions

- Remove Min, Max, Avg fields from MetricSummary struct (never read, displayMetric recalculates stats from Data)
- Remove dead calculateStats call and field assignments in GetMetricSummary
- Remove unused calculateMin and calculateMax helper functions
