feat(locale): Phase 2 — 모든 사용자 노출 Korean 문자열 → strings.xml 추출 + 영문 번역

Sub-agent 작업 결과:
- values/strings.xml + values-ko/strings.xml 각각 71 → 194 줄 (약 85 신규 string)
- 17 파일 수정 (UI views 9개, components 3개, managers 1개, services 2개)

상세:
- ui/views/{home, consent, registration, reminder, monitoring (3), personalization, connection}
- components/{BatteryWarningBanner, FirmwareWarningBanner, LockableSlider}
- managers/AlignmentAdvisorV2 — Out/AdvisorState 에 msgKey + msgArgs 추가 (UI 가 context.getString 으로 localize)
- services/{ReminderService, BleForegroundService}

의도적으로 skip:
- ClinicalHomeView / ClinicalLiveView (R&D-only dev mode)
- PiezoMonitoring dev panel labels (dev 도구)
- AlignmentAdvice / 2-phase AlignGuide (UI 미사용)
- 이미 영어인 파일들 (Onboarding, Pin, SensorSelect, Calibration 등)
