refactor: use discord.js avatarURL()

- Replaces manual avatar CDN URL construction with Discord.js's `avatarURL()` methods.
- Defaults to optimized formats like webp instead of the previously hardcoded .png for non-animated avatars,
which significantly reduced avatar size (e.g., from 24 KB to 1 KB).
