fix: missing event ID in rejection loggers

[Ferryx349]

Description

There is a bug in the EventMessageHandler where the logger is using string formatting (%s) but missing the corresponding event.id arguments. As a result, the logs will literally output event %s rejected... instead of replacing %s with the actual event ID, which will make debugging difficult.

This happens in two places inside src/handlers/event-message-handler.ts when an event is rejected for being expired or rate-limited.
