⌚ fix: Wait for Initial Message Save & Correct Latest Message (#3399)

* chore: assistants, unsupported assistant, better logging

* chore: remove unnecessary logger in validateAssistant middleware

* fix: resolve initial conversation save/promise before saving response

* chore: Import and organize dependencies in Speech component

* fix: conversation statefulness
- Latest Message (at index 0) should not be reset if existing convo
- add debugging context for clearAllLatestMessages
- Added logging concerning latest Message updates (dev mode only)
- update latest message Set logic, also checks for change in conversation Id
- consolidated latest message helpers to client/src/utils/messages.ts
