visitor profile/summary: show what visitor likes in ecommerce

[hpvd]

as a follow up of "visitor profile/summary: show what visitor likes #10516"
it would be great to have also the product orientated ecommerce view of things a visitor likes:

"Visitor likes most:"

• page with url
• page title
• Product with SKU
• Product with Name
• Product with Category

showing for each of these five topics:

• list of repeated visits once with number of how often
• list of most length visiting time (summed) with number of how many seconds

[hpvd]

of course it would be good to gave this information accessible via API like other things in visitor summary
(see #12049)
