test: reconcile settings tests with universal right-click paste and promoted worktree symlinks

Merging main surfaced two semantic conflicts against this branch's tests:

- #8322 exposed right-click paste on every platform, so the settings
  navigation metadata now indexes it even when only the terminal host is
  Windows. Update the stale assertion accordingly.
- #8318 promoted APFS worktree shared paths by dropping the
  experimentalWorktreeSymlinks gate, so WorktreeSymlinksSection now always
  mounts inside RepositoryPane and reads window.api.fs. Stub a minimal
  renderer fs bridge in the pane test, matching the AppearancePane pattern.
