/**
 * 配置中心提示词/词表/凭据编辑模型单元测试（Phase 3 Task 7b + 7c）
 *
 * 钉住 src/views/config/center/model.ts 的纯逻辑契约（事实源：
 * app/platform/config_validation.py 的 PROMPTS_SIZE_CAPS 与
 * app/engine/wall_schema.py 的结构/双形态正则条目约定）：
 * - 提示词：UTF-8 字节口径（中文 3 字节/字）、50/100KB 上限判定、
 *   原样快照 → 表单值的防御归一；
 * - 词表：正则条目双形态（纯字符串 | {pattern, flags, comment}）的
 *   解析/序列化往返、空行剔除、语言池清洗、initWallEdit 对透传键的
 *   保留、buildWallPayload 的整组重组；
 * - 变体键镜像：reminders 六类 / cc_templates 四组与后端常量同构；
 * - 凭据三组（Task 7c）：normalize（掩码哨兵态/数值转串/缺键防御）、
 *   build（密钥哨兵往返——不动保存回 '__SET__' 保持库值；空串 = 清空；
 *   新值优先；数值空串 → null）与 validate 前端预检（端口 1-65535 /
 *   邮箱含 @ / push URL 协议与正数·1-10 整数边界，与后端校验同款）。
