🛠️ fix: Improve SSE Handling and Fix Typo in sendEmail Template (#1245)

* fix: typo for passwordReset.handlebars

* fix(useSSE): prevent unnecessary JSON.parse abort error, handle immediate abort-submit gracefully by reverting to previous state before immediate abort-submit, add showStopButton state to explicitly render disabled sendButton when message generation is cancelled, filter undefined messages and replace undefined convo for cancelHandler
