Translation: FileException Does Not Support Translation

Is there an existing issue for this?

• I have searched the existing issues

Problem description

Problem Description:

There is one generic Base::FileException that includes a hardcoded string which gets bubbled up into a user message when anything related to files or file systems goes wrong. These exceptions should be revisited and reworked to use the best translation methods available in freecad.

• This is a further action from issue #25474

Proposed Solution:

Method A: Add more granular derived exceptions from Base::FileException to communicate different problems, and include text/translation in their class definition instead of the point when the exception is raised. This is the proposed method from @chennes .

Method B: Include translation code at the point the exceptions are raised.
