[Feature] Admin Panel Localization

[rafaelvieiras]

Is your feature request related to a problem? Please describe.
Yes, the request is related to the need for multi-language support in the OpenMU Admin Panel, as discussed in Issue #355. The lack of localization in different languages can be a barrier for administrators who are not familiar with English.

Describe the solution you'd like
I would like to suggest the implementation of a localization system for the Admin Panel, allowing it to support multiple languages. A possible approach can be found in this Gist, which describes a way to use PO files for localization in .NET projects, which may be applicable to OpenMU.

Additional context
Localization not only makes the software more accessible to users from different linguistic backgrounds but can also contribute to expanding the user and developer community worldwide, bringing new perspectives and collaborations to the project.
