Behavior-preserving; 271 BattleNode/Matching/Services tests green, full solution builds. "BattleType" meant two things: the Sessions.BattleType enum (Pvp/Bot) and an int "mode id" field. Renamed the int field on MatchContext AND the BattleStartBody wire DTO to BattleModeId (wire key stays "battleType" via JsonPropertyName), so BattleType now means only the enum project-wide. New Bridge/BattleModes.cs (TakeTwo = 11) replaces every 11 literal — both prod MatchContextBuilder sites and the test fixtures/assertions. The arbitrary-passthrough 42 and bot 0 stay literal.
