feat(gui): Migrate to Tauri events

- Replace Electron IPC with Tauri invoke() for API calls
- Implement TauriSwapProgressEvent for state management
- Remove IpcInvokeButton, replace with PromiseInvokeButton
- Update models: new tauriModel.ts, refactor rpcModel.ts
- Simplify SwapSlice state, remove processRunning flag
- Refactor SwapStatePage to use TauriSwapProgressEvent
- Update HistoryRow and HistoryRowActions for new data structures
- Remove unused Electron-specific components (e.g., RpcStatusAlert)
- Update dependencies: React 18, Material-UI v4 to v5
- Implement typeshare for Rust/TypeScript type synchronization
- Add BobStateName enum for more precise swap state tracking
- Refactor utility functions for Tauri compatibility
- Remove JSONStream and other Electron-specific dependencies
