refactor: internal id handling

[theEvilReaper]

Proposed changes

Currently, the game uses ID values to represent teams, states, and other entities. These IDs are globally scoped, which makes it difficult to understand what each ID represents and where it is used. The goal of this pull request is to isolate IDs and limit them to their respective contexts. This makes it clearer what each ID is intended for.
