🐛fix: Fix message saving missing the last conversation

- Modify saveMessagesImmediately to accept messages parameter
- Pass updated message list to all save calls instead of relying on closure
- Ensure complete message history is saved including the last message
- Fix timing issue where old message state was being saved

This fixes the issue where the last conversation was not being persisted to localStorage.
