fix: Prevent potential segfaults by deep copying event payloads

- Added deep copy of event payloads in multiple modules to avoid segmentation faults when events are freed.
- Updated the handling of payloads in ChannelManager, MessageHandler, DiscordBridgeService, MapUploaderService, and PacketCaptureService to ensure safe access to event data.
- Enhanced logging for cases where payloads are missing, improving error handling and debugging capabilities.
