Criteo OneTag loaders need partner ID a

Criteo documents the loader as ld.js?a= plus your Partner ID. Without a, the dedicated library never loads. gum.criteo.com cookie matching is not this pack.

Rules

Codes are stable. A finding in CI, MCP, or the playground lands on the same id.

Field	Required	What it checks	Rule ids	Source
`a`	required	It is the numeric Criteo Partner ID. Criteo documents the loader as `ld.js?a=` plus that ID. Fix: Set `a` to the Partner ID Criteo issued for the OneTag.	`vendor.criteo.param.a.missing` `vendor.criteo.param.a.empty` `vendor.criteo.param.a.invalid`	docs
