Adform tags need banner number bn

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
`bn`	required	It is the numeric Adform banner ID. Adform documents video tags as `{region}.adform.net/videoad/?bn=` plus that ID. a2 is the Americas tracking domain, track is EMEA, a1 is global, asia is APAC. Fix: Set `bn` to the banner ID from the Adform tag.	`vendor.adform.param.bn.missing` `vendor.adform.param.bn.empty` `vendor.adform.param.bn.invalid`	docs
`C`	optional	It is the click index Adform writes on multi-click banners. Adform documents clicktrackers as `C=1`, `C=2`, and so on. Single-click tags omit it. Fix: Set `C` to the click index from the Adform tag, or drop the pair on a single-click tag.	`vendor.adform.param.C.empty` `vendor.adform.param.C.invalid`	docs
`cpdir`	optional	Adform documents cpdir as the absolute replacement landing page URL.	`vendor.adform.param.cpdir.empty` `vendor.adform.param.cpdir.invalid`	docs
`urlappend`	optional	Adform appends query data to the landing page. Its supported __ADFSEP__ macro resolves to ? or & depending on the destination query.	`vendor.adform.param.urlappend.empty` `vendor.adform.param.urlappend.invalid`	docs
