fix: Use different OAuth App ID for GitHub Enterprise

[jtyr]

What does this PR do?

This PR fixes #3936 by using a different OAuth App ID for GitHub Enterprise login process. The reasoning and more details are described in my comment in that issue.

How did you verify your code works?

bun install
bun dev auth login

I was able to login to our ghe.com instance like that and then use Copilot via OpenCode.

PR #6974 - "fix(tui): enable GitHub Copilot Enterprise authentication in /connect…"

• fix(tui): enable GitHub Copilot Enterprise authentication in /connect… #6974

Why it might be related: This PR also addresses GitHub Enterprise authentication. Since PR #11990 is specifically about fixing the OAuth App ID for GitHub Enterprise login, and PR #6974 is about enabling GitHub Copilot Enterprise authentication, they may be working on the same underlying authentication issue or related features.

I'd recommend checking PR #6974 to see if it's already addressing the same issue (#3936) or if the approaches overlap.

I don't think PR #6974 is necessary for copilot oauth ghe login, I've build based on these commits and I was able to do a fresh ghe login:

opencode$ git log -3 --oneline

@MarkSchmitt PR #6974 adds support for connecting Github Enterprise from the TUI using the /connect command. Right now, /connect only works with github.com and does not provide an option to connect to GitHub Enterprise so that PR is unrelated with this PR

Unfortunately we need to setup an actual enterprise app on github to comply w/ rules. Let me see what id u are using here

GitHub Copilot CLI OAuth App ID

[rekram1-node]

Yeah they dont want us to do that unfortunately, waiting for github app process to complete

The OpenCode OAuth has been approved for GitHub Enterprise so this workaround is not needed anymore.
