Pull request overview

This PR fixes issue #1993 where SSE connections fail with "Response head already sent" when users have missed messages in MongoDB. The fix is achieved by refactoring the SSE functionality into a dedicated connector-web-sse module and ensuring proper operation ordering.

Changes:

• Created new connector-web-sse module to isolate SSE-related functionality for better maintainability
• Fixed the SSE connection bug by ensuring setupSSE() is called before sendMissedEvents(), preventing writes before headers are configured
• Migrated from deprecated applicationId to connectorId and changed recipientId from PlayerId to String for consistency
