Implement hybrid local/API thread storage with message persistence

- Add local-first thread and message storage using Redux Persist
- Persist threads, messages, and UI state (panelWidth, lastViewedAt, selectedThreadId) locally
- Remove API dependencies for thread/message fetching (fetchThreads, fetchThreadMessages)
- Add local thread management actions (createThreadLocal, deleteThreadLocal, addMessageLocal)
- Fix message persistence issue: ensure both user and AI messages survive navigation
- Maintain API integration for sendMessage functionality with AI responses
- Preserve optimistic updates and error handling behavior
- Enable instant app startup and offline conversation viewing

Key changes:
- Enhanced threadSlice with messagesByThreadId storage and local management actions
- Updated Redux persist config to include thread data
- Modified Conversations component to use local thread operations
- Fixed addInferenceResponse to persist preceding user messages
- Maintained all existing UI patterns and error states
