Fix hydratation issues. Refactor OpenCompleteForm and app.vue for Improved Component Structure

- Wrapped `feature-base`, `SubscriptionModal`, and `QuickRegister` components in a `ClientOnly` tag within `app.vue` to enhance rendering behavior and prevent server-side rendering issues.
- Removed commented-out code in `OpenCompleteForm.vue` to clean up the component and improve readability.

These changes aim to improve the overall structure and maintainability of the components by ensuring proper rendering and clarity in the codebase.
