[FIX] mail: fixes document viewer's url preview

This commit fixes the document viewer: the document viewer
was altering the `type` key of attachment objects, this issue was causing
matching errors in some cases.

With this commit, the document viewer widget uses its own key `attachment.fileType`
to store the information that used to override `attachment.type`

closes odoo/odoo#32414
