 * @description Retrieves paginated list of daily closing reports with optional filtering by location, date range, and status
 * @param {NextRequest} request - HTTP request with query parameters: location_id, start_date, end_date, status, limit (default 50), offset (default 0)
 * @returns {NextResponse} JSON with success status, array of closing reports, and pagination metadata
 * @example GET /api/aperture/finance/daily-closing?location_id=...&start_date=2026-01-01&end_date=2026-01-31&status=completed
