fix: BLE TX 먹통 해결 및 메모리 안전성 개선

- binary_tx_handler를 dr_binary_tx_safe로 전체 교체 (APP_ERROR_CHECK 제거)
- data_tx_handler APP_ERROR_CHECK → DBG_PRINTF 교체
- memset/memcpy 하드코딩 크기를 define 상수로 교체 (버퍼 오버런 수정)
- SERIAL_NO_LENGTH, HW_NO_LENGTH, PASSKEY_LENGTH를 main.h로 통합
- 미사용 HW 드라이버/EEPROM 코드 삭제, TWI를 i2c_manager.c로 통합
- EEPROM → FDS 전환, 코드 리뷰 현황 문서 추가
