fix: custom oauth binding status never shown due to id type mismatch

[feitianbubu]

⚠️ 提交说明 / PR Notice

个人资料页「账户绑定」里，自定义 OAuth 提供商永远显示「未绑定」，即使 user_oauth_bindings 表里有绑定记录。

原因：后端 /api/user/oauth/bindings 返回的 provider_id 是 JSON 数字（Go int），前端却用 b.provider_id === String(provider.id) 严格比较，数字和字符串永远不相等，所以 isBound 恒为 false。另外前端接口声明的 external_id 字段后端并不返回（实际字段叫 provider_user_id），绑定卡片上也一直显示不出第三方身份 ID。

改法：前端类型声明对齐后端响应（provider_id: number、provider_user_id），按数字直接比较，卡片显示改用 provider_user_id。

Walkthrough

Custom OAuth binding types now use numeric provider IDs and provider_user_id. Account binding lookup, display, and unbind calls use the updated identifiers.

Changes

Custom OAuth binding updates

Layer / File(s)	Summary
Align custom OAuth binding contract and account display web/src/features/profile/api.ts, web/src/features/profile/components/tabs/account-bindings-tab.tsx	CustomOAuthBinding uses numeric provider_id and optional provider_user_id. unbindCustomOAuth accepts a numeric provider ID. Account binding lookup compares provider IDs directly and displays provider_user_id.

Poem

A rabbit hops through OAuth bright,
With numbered keys aligned just right.
User IDs now show their name,
Bind and unbind share the same game.
Nibble, click, and ship tonight!
