Add Spanish language support 🇪🇸

[IsmaelVazquez]

Hi!

I would like to suggest adding Spanish as an available language in Coolify.

Coolify has a growing Spanish-speaking community, and having the interface available in Spanish would make the platform more accessible to many users.

I’d also be happy to help translate Coolify into Spanish if needed. I can contribute with the initial translation and help review or maintain it over time.

If there is already a translation system or a preferred way to contribute translations, please let me know and I’ll be happy to help.

Thanks for the great work on Coolify!
