Add AvatarData into the chat reaction setup

[CapoMK25]

Brief description

Closes #861

Implements AvatarData into the chat reaction setup successfully. On top of successful unit tests (when ran individually), backend testing for this was done through in-memory script execution, here's the output:

[capomk@archlinux Altzone-Server]$ npx ts-node -e "
import 'reflect-metadata';
import { plainToInstance } from 'class-transformer';
import { ReactionDto } from './src/chat/dto/reaction.dto';

const sampleReaction = {
  playerName: 'ShadowKnight',
  emoji: '🔥',
  sender_id: '64f1a2b3c4d5e6f7a8b9c0d1',
  avatarData: {
    head: { id: 1, color: '#ff0000' },
    hair: 2,
    skinColor: '#FAD9B5'
  }
};
   
const result = plainToInstance(ReactionDto, sampleReaction, { excludeExtraneousValues: true });
console.log('Transformed ReactionDto:\n', JSON.stringify(result, null, 2));

Change list

• Adds new imports to addReaction.dto.ts just for the DTO in question, at least for the most part.
• Adds the AvatarData as an optional DTO in the same file with the imported functionality included.
• Similar setup on reaction.dto.ts as well.
• Implements the avatarSchema on reaction.schema.ts.
• baseChatService.ts and chat.service.ts were modified for the sole purpose of getting npm run build to pass. I followed the same setup that's been done on the previous parts of the async method, making sure to add the required fields to the class to make it work.
