* fix(github): hide approve PR button on own PRs and reject self-approval server-side
The frontend's existing self-author check failed open when the current
GitHub user hadn't loaded yet — the PR panel didn't call useGitHubStatus,
so the green Approve button flashed on every PR (including your own)
during the brief window before /api/v1/github/status resolved.
Fail closed when the user is unknown, fetch the status from the panel,
and add a typed ErrSelfApprove guard in Service.SubmitReview so any path
that bypasses the visibility check gets a clean 422 instead of an opaque
upstream error.

* test(github): cover controller's self-approve 422 mapping
Address PR review feedback: add TestHttpSubmitReview_SelfApproveReturns422
to exercise the controller → service → 422 path end-to-end so a future
refactor can't silently reclassify ErrSelfApprove as a generic 500.
