Refactor giveaway job processing and enhance environment documentation

- Improved handling of the `giveawayCreate` job in the bot's job processing for better consistency.
- Updated `.env.example` to clarify the usage of `BOT_TOKEN` for both the bot and WebUI.
- Added `bullmq` dependency to the WebUI package for enhanced job management capabilities.
