sig#882 - Define Languagefile for ErrorMessages

[MaximilianHauer]

Description

sig#882 - Refine Backend Error Messages

• Create a centralized file that contains all necessary information, including error codes, languages, and corresponding messages.
• Enable the frontend to fetch the error code from the backend and pull the respective error message from the resource file to display it to the user.
• Ensure the file is easily configurable, allowing for straightforward updates to error messages.
• Avoid technical jargon or cryptic error codes, and instead focus on describing the issue in plain language.
  NOTE: Should be evaluated if we provide a file per language.

Steps

• Create an Error.json file per language
• list all errorcodes with the error-text from the backend
• refine the error-text in english if you see improvements to raise the understanding
• translate the error file to german (use genext ;) )
