fix(desktop): place daily review selector below trigger

[Astro-Han]

Summary

At the 480px window floor, the Daily Review analysis-model selector used Astryx Selector’s default selected-item overlay behavior, so the open popover could cover its trigger and violate the existing Storybook bounds contract.

Set the selector’s existing placement seam to below, matching the settings-row selector layout already used by the default permission control. This keeps the popup within the row/page bounds without shared CSS or parallel positioning logic.

Verification

• Existing product-settings-pages--daily-review-model-selector-open-narrow @ floor geometry reproduced before the fix: trigger 446.98..466.98, popover 442.98..580.98 (overlap)
• Focused built-Storybook smoke with the locked Playwright Chromium passed at 480px in light and dark: popup 472.98..610.98, below trigger 446.98..466.98
• npm --workspace @maka/desktop run build-storybook
• npm --workspace @maka/desktop run typecheck
• npm run format:check
• Full storybook-visual-smoke.mjs run reached and passed both target floor jobs on the baseline build; the overall run still reports the unrelated pre-existing design-system-icons--lucide-icons catalog render failure

Checklist

• Tests cover the change and fail without it
• Format, typecheck and the affected Storybook smoke pass locally
