feat: Add visibility component to dynamic zones

[jaserNo1]

Description

Adds a shared visibility component that allows hiding dynamic zone components in the Strapi backend.

Changes

• Added shared/visibility component with isVisible boolean field
• Updated all dynamic zone components to include the visibility component
• Modified frontend manager.tsx to filter out components with isVisible=false

Use Case

Content editors can now hide specific dynamic zone sections without deleting them, useful for:

• A/B testing
• Seasonal content
• Draft sections
• Temporary content removal

Testing

1. Add a dynamic zone component in Strapi
2. Set visibility to hidden
3. Verify component doesn't render on frontend
