* Migrate ConversationContext to createInterfaceApi pattern
This migrates ConversationContext following the migration of AIChatContext, and leaves
UntrustedConversationContext (and associated API binding classes) alone,
in the interest of making an effort to minimize the branch sizes.
Context Changes:
- conversation_context.tsx: Uses generateReactContextForAPI with new ConversationProvider
API Changes:
- Use new (previously added) API wrapper exported from `api/conversation_api.ts`
- Remove old binding functions from api/index.ts in favor of new (previously added) bindings in `api/bind_conversation.ts`
- state/mock_context.tsx: Update test context wrapper to include ConversationContext and API data
Test and Storybook Updates:
- Now use MockContext from state/mock_context.tsx for ConversationContext
