Preserve the shown selection's traits in mixed scopes.

If environments use the same instance and model with different effort values, these mixed flags are true. Passing null makes pickModelSelection discard the shown environment's options. Re-picking then submits an option-free selection across the scope.

Pass selection for the default picker and the representative stored fallback selection for the fallback picker, including when mixed. The final PR objective requires mixed-scope re-picks to apply the shown environment's traits.

Also applies to: 293-293

Review comment at @apps/web/src/components/settings/ProjectDefaultsSettings.tsx at line 175:
Update the `pickModelSelection` call in the default picker to pass the shown `selection` even when `mixedModel` is true, and update the corresponding fallback picker to pass its representative stored fallback selection. Mixed-scope re-picks must preserve the shown environment’s options rather than creating an option-free selection.

Keep representative traits when resolving mixed writer and review-guide settings.

If environments have different traits for the same instance and model, these expressions pass null. pickModelSelection then removes the representative selection's options from the submitted update.

Pass reviewGuideSelection and activeSelection even when mixed. This makes re-picking apply the shown environment's traits across the scope, as the final PR objective requires. Picks of another instance or model will still create a fresh selection.

Also applies to: 572-572

Review comment at @apps/web/src/components/settings/SourceControlWritingSettings.tsx at line 369:
When writer or review-guide traits differ across environments for the same instance and model, passing null causes pickModelSelection to discard the representative selection’s options. Update the mixed-setting arguments in SourceControlWritingSettings to pass reviewGuideSelection and activeSelection even when mixed, preserving the shown environment’s traits when re-picking; selecting a different instance or model should continue to create a fresh selection.
