Subject: [PATCH] chore(migrations): add migration script for
 ivanti_counts_history table
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Standalone migration script for consistency with other files in
backend/migrations/. The table is also created automatically at server
startup via CREATE TABLE IF NOT EXISTS in initTables() so no manual
step is required on the dev server — just restart the backend after
pulling.

+// Migration: Add ivanti_counts_history table
+//
+// Stores a snapshot of open/closed Ivanti finding counts on every sync.
+// Unlike ivanti_counts_cache (single-row, always overwritten), this table
+// accumulates all snapshots so time-series charts can be built from it.
+//
+// The GET /api/ivanti/findings/counts/history endpoint aggregates these rows
+// to the last snapshot per calendar day using a ROW_NUMBER window function.
+//
+// NOTE: This table is also created automatically at server startup via
+// CREATE TABLE IF NOT EXISTS in initTables() (ivantiFindings.js).
+// This script is provided for manual setup on fresh installs and for
+// documentation consistency with other migration files.
+//
+// Usage: node backend/migrations/add_ivanti_counts_history_table.js
