refactor: 代码审阅优化

P0:
- fix(config): config_dir 使用 home_dir 回退，避免 ~ 不展开
- fix(search): 模糊查询转义 LIKE 通配符 % 和 _

P1:
- chore(db): 连接池添加 acquire_timeout 10s
- refactor(update): 消除 meta_keys/secret_keys 重复计算

P2:
- refactor(config): 合并 ConfigAction 枚举
- chore(deps): 移除 clap/env、uuid/v4 无用 features
- perf(main): delete 命令跳过 master_key 加载
- i18n(config): 统一错误消息为英文
- perf(search): show_secrets=false 时不再解密获取 key_count
- feat(delete,update): 支持 -o json/json-compact 输出

P3:
- feat(search): --tag 支持多值交叉过滤

docs: 将 seed-data.sh 替换为 setup-gitea-actions.sh
