DS Epic: Table Header

### **Description**

A Table Header component defines the top row of a table, displaying the titles of each column to organize and label the data below. It enhances readability and helps users quickly understand the structure and content of the table.

The issue provides no files, tests, or entry points to inspect. Start by locating the design-system component structure and existing table components; done should mean the requested Table Header component is defined with its column-title behavior and validated consistently with the project’s existing conventions.
