fix(gateway,runtimeconfig): 渠道配置写路径改为 patch 语义,修凭据静默丢失(P0 级数据安全)
CI / Backend (build / vet / test / cross-compile) (push) Has been cancelled
CI / Frontend (tsc + vite build) (push) Has been cancelled

- 新问题(本轮前端组发现):config 是整条替换,而面板只发送用户本次碰过的平台字段 ⇒
  ① 保存微信(iLink)账号卡(其平台字段只有 cdn_base_url,甚至可为空)会把
  bot_token/bot_id/owner_id/get_updates_buf **全部抹掉**(iLink token 是长期凭据);
  ② Telegram 填 webhook_url 而不重填 token 会因 cleanAccounts「token 空即丢账号」把**整个账号**删掉
- 修法:新增 runtimeconfig.PatchChannel + mergeChannelConfig + isEmptyConfigValue(三态,与 personaId 同构)
  · 键省略 / config 整体缺席 / null = **保留已存值**(未给出的键绝不被抹掉)
  · 给出非空值 = 覆盖 · 显式 null 或 "" = **清除该键**(0/false 不算空)
  · 写路径 UpsertChannel → PatchChannel;非 config 字段(名单/限流/personaId)仍整值替换(不变)
- 回归(真断言落盘内容):微信卡片只带 cdn_base_url / 空卡片三种形态 → 四个凭据键全在;
  Telegram 只带 webhook_url → 账号存活且 token 不变;显式 null/"" → 键真被清除;新账号正常写入;
  既有 TestAdminSaveChannelConfigPersistsAndReloads 保持绿
- 变异反证 3 条(改回 UpsertChannel → 精确复现两缺陷;去掉清除分支;"" 不再算空)均已还原
- 边界未改:token 要求型平台**显式**清 token 仍按 cleanAccounts 丢账号(主人明确清除凭据的语义);
  「本次一个 config 键都没给出」在非 weixin-ilink 平台仍回 400(既有行为,不在授权内放宽)

// PatchChannel 以 **patch 语义** 写入一个账号,是 UpsertChannel 的补丁版:
// acct.Config 被当作「只含本次请求显式给出的键」的补丁,而不是一整套完整配置。

// - 补丁里**缺位的键** → 保留该账号已存值(未被触碰的键绝不因一次保存被抹掉);
// - 补丁里给出的非空值 → 覆盖该键;
