feat(web): token 数以 K 输入显示,已存凭证显示掩码占位(FIX-8)

- 新增 UnitInput 与 kind=tokens:上下文预算、单次 token 上限、自定义模型上下文窗口以 K 输入(允许小数),存储仍为原始 token 数;校验与提示用 K 表述;列表/详情 token 数统一 K/M 简写(formatTokens)
- 新增 SecretInput 与 kind=secret:已保存时显示「已设置 ••••••••」(有服务端掩码时带末 4 位),聚焦直接输入替换,留空保持,「清除」确认后保存生效;替换模型服务、TMDB、网页搜索、下载器、媒体服务器、浏览器服务、站点账号、Passkey、本机 Token 各处
- 统一只写凭证服务端语义:省略或空串 = 不变,null = 清除(contracts secretInput);下载器/媒体服务器新增清除;站点凭证同类更新可留空保持密码/Cookie/API Key/TOTP,TOTP 可 null 清除,不再误删 TOTP 与 UA
- contextBudget 最小值 4096→4000、contextWindow 1024→1000,便于按 K 填写
- 测试:换算与校验、SecretInput 渲染与状态、各接口留空不变/显式清除
