refactor: rename Bot to Tribe in internal execution code (#3372)

## Description

Follows up on #3290 which renamed the user-facing "Bots" to "Tribes".
This renames the internal implementation to match:

- `BotExecution` → `TribeExecution`
- `BotSpawner` → `TribeSpawner`
- `BotNames` → `TribeNames` (`BOT_NAME_*` → `TRIBE_NAME_*`)

All callers updated accordingly. `PlayerType.Bot` and `ColoredTeams.Bot`
are intentionally left unchanged as they are serialised wire-format
values.

Closes #3335

## Please complete the following:
