fix: add groupName to ExecutionSummary, locale format stat values, inspect column, fix duplicate keys

- Added groupName field to ExecutionSummary Java record and OpenSearch mapper
- Dashboard stat cards use locale-formatted numbers (en-US)
- Added inspect column (↗) linking directly to exchange detail page
- Fixed duplicate React key warning from two columns sharing executionId key
