🔀 :: perf 성능 측정 CI 동작 수정

[aiden30015]

개요

성능 측정 CI(perf.yml)가 실제 앱을 빌드/실행하면서 드러난 문제들을 수정합니다. 관련 이슈 없이 진행하는 PR입니다(예외).

변경 사항

• Gradle 8.12 → 8.14.3, AGP 8.9.1 → 8.11.1, Kotlin 2.1.0 → 2.2.20 (Flutter 최소 요구사항)
• main() 초기화를 bootstrap(overrides)로 분리 (프로덕션 동작 불변)
• 온보딩 로그인 버튼, 멤버 리스트에 테스트용 Key 추가
• integration_test/perf_test.dart 재작성, fake repository 추가
• riverpod 직접 의존성 추가

검증

더미 PR #144에서 perf 워크플로우 5/5 시나리오 통과 확인 (run 35430653586)
