chore(battle-node): delete dead ScriptedProfiles.Opponent{Matched,BattleStart}Profile fields

Phase 2 absorbed the scripted opponent cosmetics + class/chara fixture
into ScriptedBotParticipant.Context; the two profile fields have been
unreferenced since (kept one phase as documentation tie-back, per PLAN.md
L104 (d)). The Context comments now describe the values directly with
frame[N] provenance instead of pointing at the deleted fields. Also
removes the now-unused SVSim.BattleNode.Protocol.Bodies import from
ScriptedProfiles.cs.

948 tests passing (unchanged).
