• Setup Google Analytics file input

If a Service Account Key File has already been uploaded, the file input will be filled with asterisks to indicate that a file is present.

A "Delete" button will now be visible. Clicking this button will trigger a confirmation popup: "Are you sure you want to remove this file?"

If the user clicks "Ok," the file data will be removed from the Google Analytics configuration in the database. If a new file is uploaded and submitted with the setup analytics form, it will replace the old one. If no file is submitted with the form, the existing file data in the Google Analytics configuration will not be removed.
