Backend

• Implement route /file/<uuid> in the validation page that returns the front with a <script> block containing a json with all the necessary metadata to display the page created in issue Validate file using UUID #130
  Estimate: 2h

Frontend

• Make changes to the page created in issue Validate file using UUID #130 to be displayed without having to make a request to the API, you only need to read the JSON that will be in a variable in the body of the page.
  Estimate: 2h

PS: The page displayed with the API request will continue to exist but will only be loaded when the user informs the UUID on the form. This issue is for the person who accesses the /file/<uuid> page. This person will access this page by clicking on the link in the PDF or by accessing the URL read in the document's validation qrcode.
