Unify show item for FAL records
Currently there are 2 different views used in the core when showing information of FAL records.
1st: Content element => IRRE => info bubble:
- shows more meta data
- shows "References from this item:"
2nd: Page module => click on the image
- preview image
- download button
- title is the file name and not the UID
- unify those to 1 and remove the other
