Add alias in graph to prevent duplicated fields in fragments

[exacs]

This PR adds alias to custom properties by prefixing the content type name:

fragment ContentType on ContentType {
  ContentType__p1:p1
  ContentType__p2:p2
}

And implements a function that removes the prefixes before returning the response to the user.

Fields that are not defined by the user are unaffected

Pull Request Overview

This PR adds GraphQL field aliasing to prevent duplicated field name collisions when generating fragments. Custom properties are aliased with their content type name prefix (e.g., ContentType__p1:p1), and the prefixes are automatically stripped from responses before returning data to users.

• Adds removeTypePrefix function to recursively remove type-name prefixes from GraphQL response data
• Updates convertPropertyField to apply aliases using the pattern {typeName}__{fieldName}:{fieldName}
• Integrates prefix removal into getContentByPath and getPreviewContent methods
