VITEC headless: ContentElementResolver, Product fields (videofile, showdatapath)

- New Classes/Service/ContentElementResolver.php: parses TYPO3 typolink
  (t3://record?identifier=tt_content&uid=N, t3://page?uid=P#N, plain numeric)
  to a normalised tt_content envelope ({id,type,colPos,sorting,appearance,
  data}), recursively resolving any nested VITEC list-plugin children.
- ProductListJsonRenderer / ProductShowJsonRenderer: contentelement and
  contentelementcta now emit the resolved object instead of the raw
  typolink string (breaking change at those two keys).
- Product model: new field videofile (FAL, single video upload in tab
  Images and Videos, mp4/webm/ogv/mov/m4v); new bool field showdatapath
  (toggle at end of General tab, controls the "Datapath is now Vitec"
  graphic in the frontend). ext_tables.sql, TCA, model property +
  getter/setter, and both renderers updated accordingly.
