refactor: Remove qmob prefix

[0ffz]

This prefix is currently being used to indicate a mob created by queenofants for another project, that was then donated to our project. This isn't clear and the prefix is quite cumbersome, instead I'd like any relevant files to have it removed and add the following comment:

# This mob file was originally created by 'queenofants' for another project
# and donated to the Mine in Abyss project with permission to modify as needed.
# It is NOT licensed under this project's license.

Checklist

Prefixes have been removed from:

• All file names
• All skills and mob names
• All model names

Attribution has been added:

• To each contributed file
