fix(copilot): align with GitHub Copilot June 2026 rule updates

- Token exchange (`/copilot_internal/v2/token`) now sends `Copilot-Integration-Id` and `X-Github-Api-Version` (openclaw PR #80074, 2026-05-10).
- `MakeAuthenticatedRequest` now sends `X-Github-Api-Version` for `/models` and other authenticated calls.
- `GetCopilotQuota` now presents the full Copilot client identity headers instead of a `CLIProxyAPIPlus` User-Agent, so `/copilot_internal/user` stays accepted under the new integration-id requirement.
- Bump `User-Agent`/`Editor-Version`/`Editor-Plugin-Version` to the community consensus (`GitHubCopilotChat/0.50.0`, `vscode/1.122.0`, `copilot-chat/0.50.0`; caozhiyuan/copilot-api v1.10.22, 2026-05-29).
- Sync the header constants across `copilot_auth.go`, `github_copilot_executor.go`, and `api_tools.go` with an explicit keep-in-sync comment.
