fix(ui): pass sourceRepo to PR/issue context calls for fork workflows (#2090) (#2091)

Fixes GitHub PR/issue context endpoints returning 404 when working
from a fork because they resolved the repo from origin remote only.

- Pass sourceRepo: status?.repo ?? null to all prContext() calls in
  PullRequestSection.tsx (5 call sites)
- Pass sourceRepo: args.pr.sourceRepo ?? null / args.issue.sourceRepo
  ?? null to NewWorktreeDialog.tsx (3 call sites: prContext, issueGet,
  issueComments)
- Add status?.repo to dependency arrays to prevent stale closures

The prStatus endpoint already resolves the correct repo through the
fork network; this change wires it through to the downstream API calls.

Closes #2090
