feat: deprecate Vue support

Summary

This PR completely removes Vue.js support from the crossmint-sdk repository by:

• Removing Vue UI package: Deleted the entire packages/client/ui/vue-ui/ directory containing the Vue implementation of CrossmintPaymentElement
• Removing Vue demo app: Deleted the apps/payments/vue/ directory containing the Vue payment demo application
• Updating workspace configuration: Removed Vue UI package reference from crossmint-sdk.code-workspace
• Cleaning dependencies: Updated pnpm-lock.yaml to remove Vue-related dependencies

A total of 28 files were deleted, removing 5,013 lines of Vue-specific code while preserving all React and Vanilla JS implementations.

Review & Testing Checklist for Human

• Search for broken imports - Verify no other packages or apps import from @crossmint/client-sdk-vue-ui or reference the removed Vue components
• Test build process - Run pnpm build:libs to ensure all remaining packages build successfully without the Vue dependencies
• Verify workspace integrity - Confirm the workspace configuration changes don't break VS Code setup or development workflows
• Test remaining UI packages - Verify that React UI (@crossmint/client-sdk-react-ui) and Vanilla UI (@crossmint/client-sdk-vanilla-ui) still function correctly
• Check example apps - Test that other demo apps (React, Next.js) still work properly after Vue removal

Recommended test plan: Run the build process, test a few remaining demo applications, and search the codebase for any remaining Vue references to ensure clean removal.

Notes

• This is part of a broader effort to deprecate Vue support across Crossmint repositories
• Companion PR in crossbit-main repo removes Vue documentation examples
• The build completed successfully after removal, indicating no immediate dependency issues
• All other UI frameworks (React, Vanilla JS) remain fully supported and unchanged
