fix: filter active contributors KPI to code contribution activity types only IN-1204

Apply isCodeContribution filter to both current and previous contributor
nodes so the Active Contributors KPI counts only code contributors,
consistent with its UI definition and the contributor chart.

 DESCRIPTION >
     Nightly copy pipe that precomputes org-level KPIs for the org page.
     Writes one row per organizationId into org_page_kpis_copy_ds.
+    Active contributors counts only code contribution activity types (commits, PRs, code reviews).
     Active contributors and critical projects use a 730-day (2-year) window.
     Trend compares current 730-day period against the prior 730-day period (days 731–1460).
