Both helpers now take the opponent's MatchContext + an explicit seed
instead of pulling ScriptedProfiles.OpponentMatchedProfile / OpponentBattleStartProfile
internally. ScriptedBotParticipant.Context fixture absorbs the cosmetic
fields previously hardcoded in ScriptedProfiles so Scripted's wire bytes
stay identical - verified by integration tests still green.
Phase 2 prep: PvP arms will call the same helpers with the real opponent
participant's Context.
