Add Asynchronous Data Table Loading

[alexandre-castelain]

Description

This merge request introduces the async option for data tables, allowing their content to be loaded asynchronously via a backend call instead of being rendered immediately. This is particularly beneficial for slow data sources or pages with multiple tables.

• With async enabled, table data loads only when needed, and not if the table is outside the user's viewport.
• Improves performance for heavy or multiple tables.
