[Feature Request] Implement GitHub account rebinding and update functionality for user profiles

[0x-wen]

Type: Feature Request

Labels: enhancement, backend, frontend, user-profile

Description

The current profile page at https://openbuild.xyz/profile lacks the ability to update or rebind GitHub accounts. A critical issue exists where GitHub username changes break account connections, with no recovery mechanism available to users.

Problem Details

❌ ​No rebinding flow: Users cannot update existing GitHub associations
❌ ​Username dependency: Connections rely on GitHub username rather than immutable user ID

Expected Behavior

🔧 Add "Re-bind GitHub account" option in profile settings
🔄 Implement backend API for OAuth reauthentication flow

Environment

​Affected URL: https://openbuild.xyz/profile
​Impacted Accounts: All users with GitHub integrations

目前不提供此功能，大部分活动或者有激励需要绑定 github 用户。如果需要可以邮件发工单。在核实用户身份后处理。

另外连接不是基于用户名的，只是用户名没刷新。你的核心问题是用户名没刷新？

没啥问题，只是看了一些常规的任务平台 ，个人资料能修改与解绑即提出了此问题
