[front] - fix: website datatable pagination (#8790)

* [front] - fix: adjust server pagination check for data sources without connectors

 - Switched the condition to initiate server pagination based on the absence of `connectorProvider` rather than the managed status.
 - This change ensures that server-pagination logic is correctly applied to data sources that don't have an associated connector provider.

* [front] - fix: correct server pagination condition for content list

 - Check for folder type data source rather than null connectorProvider for server pagination flag.

* [front] - fix: ensure server pagination for folders without search

 - Correct the conditional for server pagination to be active for folders as long as there's no active search query
 - Add a missing semicolon to conform with the code style conventions
