chore(hmos): 导入生产环境鸿蒙工程

- 以 D:\SmartSenior 生产工程为源，纳入 AppScope、entry、cjagent、hvigor 及根配置
- 移除 build-profile.json5 的 signingConfigs（p12/p7b/cer 路径与加密口令）及 products.signingConfig 引用
- 不纳入本地与开发产物：local.properties、.idea、.hvigor、.codegenie、demo、backup_a2a_native、SESSION_LOG.md、build_err.txt、build/、oh_modules
- .gitignore 追加 .codegenie 与密钥文件通配（*.p12/*.p7b/*.cer/*.jks/*.keystore/*.pem）
