refactor(cb): 분리 모듈 단일문자 지역변수 의미명으로 개명

손댄 모듈(screens·navigation·layout)의 단일문자 Lua 지역변수를
의미가 드러나는 이름으로 변경(규칙 시연):
- ActivateUIGroups: grp/n/g → enableGroup/name/group
- RenderSoulLabel: s → soulPoints
- BindLobbyButtons: e/fn → entity/handler
- GoLobbyMap: lp/go → localPlayer/tryTeleport
- TeleportToActMap: lp → localPlayer
- PositionMonsterSlot: m/tr/wp/e → monster/transform/worldPos/slotEntity

검증: cbset = 위 6개 메서드만 본문 변경(추가/삭제 0), cbgap GAP 0, 테스트 93/93.
산출물 재생성(SlayDeckController.codeblock) 포함.
