Support

You cannot do that with Admin Tools' URL Redirection feature, nor with Joomla's Redirection component since neither supports wildcards. This is something you'd have to do by writing custom .htaccess, web.config or NginX configuration code depending on your server.

The lack for wildcards support was a deliberate choice. Wildcards are powerful and dangerous. It's easy to make a redirection that loops forever using wildcards, rendering your site immediately inaccessible. The worst part for us is that this is such an abstract concept that most people would end up using it to shoot their feet and it'd be really hard to explain to them why they used it wrong. The people who could grasp it and use it without much drama are those who can already do that via other means. Therefore we chose not to provide this feature.

First of all, not seeing the modules in a template is NOT A SECURITY ISSUE. Usability? Yes. Security? Hell no. Not seeing modules doesn't mean you are hacked. Words have meaning and using them outside of that meaning makes it impossible to hold an intelligible conversation.

Now, about the redirection. Off the top of my head:

RewriteRule ^/components/tags/tag/(.*) /etiquetas/$1 [R=permanent,L]

This would need to be added in the custom code to add at the top of the file so it precedes all other rewriting rules. The R=permanent tells Apache 2.4 or later to use a permanent redirection so that search engines don't try to index the URL you don't want to use on your site. If you have an older Apache version replace [R=parmanent,L] with [R,L]. The L flag is important, it tells Apache to stop processing rewrite rules and just do the redirection.
