fix: Use OCCURRENCE_STATS_EXCLUDED_ATTRIBUTES_PUBLIC_ALIAS in run_stats_query

The OCCURRENCE_STATS_EXCLUDED_ATTRIBUTES_PUBLIC_ALIAS constant was defined but never used,
causing system-level identifiers (id, trace, group_id, etc.) to be included in occurrence
stats query results. This adds filtering logic to skip these excluded attributes after
translating internal names to public aliases, matching the pattern used for spans stats.
