create function for calculating product progress

[META-DREAMER]

Takes in product info and returns a % progress it has based on what collaborators, assets and stage the product is in. e.g. if has design files, brand, wearables, content, etc the score goes up.

CoPilot psuedocode:

export const getProductProgress = (product: ProductWithFiles) => {
  const { product_stage, clo3d_file, content, design_files, wearable_files } =
    product;

  const { name: productStageName } = product_stage;

  if (productStageName === PRODUCT_STAGES.rejected.name) {
    return 0;
  }

  if (productStageName === PRODUCT_STAGES.fulfillment_completed.name) {
    return 100;
  }

  const progress = [
    clo3d_file,
    content,
    design_files,
    wearable_files,
  ].reduce((acc, files) => {
    if (files.length > 0) {
      acc += 25;
    }
    return acc;
  }, 0);

  return progress;
}
