Fix: Rename tailwind.config.js to .cjs in Admin package

The Admin package uses 'type': 'module' in package.json, which treats .js files as ESM.
However, tailwind.config.js uses CommonJS syntax (module.exports).
Renaming it to .cjs explicitly tells Node and build tools to treat it as CommonJS,
resolving build errors related to ESM/CJS interop.
