fix: prettier tailwind path for save on format

[YvetteNikolov]

Het sorteren van Tailwind classes met format on save doet het weer. Was gedoe met het resolven van een path in node_modules, maar ook als je 'm hebt gesymlinked om te testen. Claude heeft z'n best moeten doen hiervoor.

Pull request overview

This PR updates @yardinternet/prettier-config to reliably locate the Tailwind stylesheet when Prettier runs via “format on save” (where process.cwd() may not reflect the project root), ensuring Tailwind class sorting works again in editor integrations.

Changes:

• Add a utility to search for the Tailwind stylesheet from multiple likely project roots (env vars, inferred root from __dirname, and process.cwd()).
• Update the Prettier config entrypoint to use this utility and only set tailwindStylesheet when found.

The __dirname.substring( 0, nmIndex - 1 ) calculation can drop the root path separator on Windows when the project lives at the drive root (e.g. C:\node_modules\...), resulting in C: (not C:\) and causing path.resolve() to base the path on the current drive CWD instead of the drive root. Use __dirname.slice( 0, nmIndex ) (optionally followed by a trim of trailing separators that preserves C:\) to reliably get the directory before node_modules across platforms.

Suggested change

	roots.push( __dirname.substring( 0, nmIndex - 1 ) );
	roots.push( __dirname.slice( 0, nmIndex ) );
