Open file dialog for mesh selection with less confusing filter (backport #3167)

[mergify]

🦟 Bug fix

Fixes #

Summary

Previous filter configuration of Open file dialog requires from user to pick an exact file format to open file. I guess it shouldn't ask user to do it. Instead it should have all supported formats (from MeshManager in gz-common repo) in one preset.
Also improved error state notification and minor spelling fixes
