Calculate permissions from the effective merged state.

If an open pull request has providerMerge and no pending merge reason, this spread reports state: "merged". viewerPermissions still comes from the open pull request, so it can include merge, close, and reviewer-edit actions. Calculate permissions from the effective state before returning the detail. Also make the merge action treat providerMerge as settled.

@packages/source-control-gitcafe/src/server/GitCafePullRequestProvider.ts at
line 680:
Update the pull request detail construction around `settledMerge(pull)` to
calculate `viewerPermissions` from the effective merged state, so an open pull
request with `providerMerge` and no pending merge reason does not retain
open-state actions. Update the merge action’s settled-state check to treat
`providerMerge` as settled.

Handle missing viewer identity before granting non-author verdicts.

If viewerActorId is absent, isViewerAuthor returns false before checking the author. If a GitHub author is identifiable only through linkedProfile.actorId and that field is absent, the author is also classified as a non-author. toViewerPermissions then returns approve and request-changes. Ensure the viewer identity is available before granting these verdicts.

lines 345 - 351:
Update isViewerAuthor and the permission logic in toViewerPermissions so approve
and request-changes are granted only when the viewer identity is available and
the author can be reliably distinguished from the viewer; treat missing
viewerActorId or a missing linkedProfile.actorId for a GitHub author as
indeterminate rather than a non-author verdict.
