## Summary by CodeRabbit

- **Style**
  - Updated various components to use dynamic theme-based colors and consistent border radius for a more unified look and feel.
  - Adjusted icon size and text styling in the file upload area for improved visual clarity.
  - Applied consistent secondary text color to informational paragraphs.

- **User Interface**
  - Changed the table header label from "Username" to "Name" and removed uppercase styling from all table headers.
  - Updated file upload instructions for clearer guidance.
