feat(scripts): add consent manager ui and internationalization

[matthewvolk]

Warning

Depends on #2643

What/Why?

Adds a consent manager UI and internationalization by integrating the C15T CookieBanner and ConsentManagerDialog with Catalyst components. The update includes:

• A cookie banner for first-time visitors
• A full-screen dialog for managing preferences based off C15T's native component
• i18n via next-intl

Testing

• First visit: banner offers accept, reject, or customize
• Accept/reject: consent persists; closes dialog
• Customize: opens dialog with accordion list; checkbox per category
• Saved preferences persist and the banner no longer appears
• Translations use the new "ConsentManager" i18n keys

Confirm the ConsentManagerProvider from @/lib/consent-manager is added to your root layout.

Migration

1. New files:

   • core/components/consent-manager/consent-manager-dialog.tsx — dialog and widget
   • core/components/consent-manager/cookie-banner.tsx — banner component

2. Layout updates:

   • Add ConsentManagerProvider around app content
   • Render CookieBanner
   • Render ConsentManagerDialog

3. i18n updates:

   • Add "ConsentManager" translations under Components.ConsentManager.Common, .CookieBanner, .Dialog, and .ConsentTypes

4. Breaking changes:

   • None; add ConsentManagerProvider, CookieBanner, ConsentManagerDialog, and translations to your layout

5. Integration:

import { ConsentManagerProvider } from '@/lib/consent-manager';
import { CookieBanner } from '@/components/consent-manager/cookie-banner';
import { ConsentManagerDialog } from '@/components/consent-manager/consent-manager-dialog';

// In your layout, ensure this is wrapped by NextIntlClientProvider
<ConsentManagerProvider>
  <YourOtherProviders>
    <CookieBanner />
    <ConsentManagerDialog />
    {/* rest of your app */}
  </YourOtherProviders>
</ConsentManagerProvider>

6. i18n keys to add:
   • Components.ConsentManager.Common.*
   • Components.ConsentManager.CookieBanner.*
   • Components.ConsentManager.Dialog.*
   • Components.ConsentManager.ConsentTypes.*

LGTM!

Unrelated but I wonder if we should remove Providers and just inline everything here.

[matthewvolk]

Yeah honestly I was thinking the same thing
