Description

This Pull Request prepares the Vite configuration for future support without the .ts extension. It ensures that the project can smoothly transition to a setup where TypeScript files no longer require the .ts extension. This change lays the groundwork for potential future changes or updates to the project's TypeScript configuration or build pipeline.

Changes:

• Updated Vite configuration to support .mts extension.
  

• Removed reliance on .ts extension for the vite configuration file.
  

• Ensured compatibility with potential future changes to TypeScript file handling.
