feat(enums): 接入 /meta/enums 权威枚举表，删掉客户端硬编码映射

客户端此前自带 platform / mood / mode 三张硬编码标签表，会与服务端漂移——
实测已经漂了：客户端把 `web` 显示成「Web」，权威表里是「网页」。

- data：MetaApi（GET /api/v1/meta/enums）+ MetaDto + MetaRepository，
  经 ApiClientFactory 创建以复用既有 token / 401 处理
- domain/enums/EnumCatalog.kt：标签查找器，**不含任何硬编码兜底表**；
  不在表内的取值一律原样返回（api-client §1.1 的未知值回落红线）；
  platformLabelOrNull 供 deviceId 前缀这类「认识/不认识要走不同回落」的调用方用；
  空 id 或空 label 一律不入表（否则角标会显示空白，或查空串凭空借到别人的标签）
- core/prefs/EnumPreferences.kt：last-good 快照，baseUrl+username 指纹闸门，
  换服务器/账号即作废，登出清空
- EnumCatalogViewModel + LocalEnumCatalog：在 CyreneRoot 注入（与 LocalAppPrefs 同套路），
  聊天角标与管理页共读同一份
- 删除 platformLabels / personaModeLabels / moodLabels；MessageSource 与 AdminFormat
  改为查表，并保留各自原有的原样回落

为什么不留硬编码兜底表：没有登录就看不到任何消息，而权威表在登录前后即会拉取，
所以 last-good 快照几乎总是存在；留着硬编码表等于把「漂移」重新引进来，而且是无声的——
旧标签和新鲜标签长得一模一样。

不转换的：trace kind/status、memory scope、thinking.mode、WS session_busy 的 mode 集合——
它们都不在 /meta/enums 内，且原本就已按原样回落。

测试：115 全绿（88 → +27：MetaDtoRealPayload 8 / EnumCatalog 7 / EnumPrefs 3 /
MessageSource 8，AdminFormatTest 改写并 +1），其中 /meta/enums 与登录响应一样
用真实抓取的响应体做夹具。
