feat: remove duplicate ad-revenue key (#81)

* feat(appsflyer): remove duplicate kAppsFlyerAdRevenueAdType key from promotion events

Remove redundant kAppsFlyerAdRevenueAdType mapping from ECommPromotionViewed
and ECommPromotionClicked handlers, keeping only the string literal
"af_adrev_ad_type" which matches the original AFEventParamAdRevenueAdType
behavior.

* fix(ci): use app token for release branch deletion

The delete-merged-action step used secrets.GITHUB_TOKEN which is
restricted to read-only by job-level permissions. Replace with the
app token that already has contents:write permission.
