feat: add upgrade modal for model upload when private models disabled

Add separate upgrade modal that displays when users without private models
try to upload models, prompting them to upgrade their subscription.

- Add upgrade modal with body, header, and footer components
- Conditionally show upgrade or upload modal based on privateModelsEnabled flag
- Integrate with subscription system via showSubscriptionDialog()
- Add localization keys for upgrade messaging
