Refactor Roles

[GalacticChimp]

Description

Roles and their handling need to be refactored. Currently we have to reference them like role[100,18]. which is cumbersome and hard to read. The rework itself seems simple, but the issue is that there are abpi 1200 such references in the code, which will take a lot of time to resolve.

Proposed change

• Rework role[100] into a human-readable enum or struct.
• Replace all references to role[100].
