There might be a delay before it gets sent, so it's better to record the time the event occurred at.
It would have been simpler to just add it to the data hash, but I felt it was an important detail for an event and should be at the top level along with event name.
In the case of order cycle opening, this is the same as opened_at. I've included this in the payload for clarity too.
It was probably better to be explicit at each test, but this one is always repeated and approaches the line length, so I wanted to just define it once at the top.
products_relation is now split in two, products_relation and
products_relation_incl_supplier_properties.
It avoids using a flag argument which is not a a good practice see:

Due to primary_taxon and supplier having moved to the variant, filtering
by_producer and by_category with a custom order involves some
complicated sql queries. So we moved the sorting logic from
ProductsRenderer to OrderCycles::DistributedProductsService so we can
keep the complicated SQL logic contained in one place
