feat(logging): Implement structured logging across the frontend

- Introduced a new `logger` module for structured logging with levels, timestamps, and styled console output.
- Replaced ad-hoc console logging with structured logger in various modules including API client, WebSocket, auth, and feature components.
- Enhanced logging in `app.rs`, `auth.rs`, `dashboard`, `messages`, `live`, and `polish` features.
- Updated UI components to include logging for user interactions and state changes.
- Rewrote `app.css` for a premium design overhaul, introducing glassmorphism, gradients, and improved responsiveness.
- Added a new `plan.md` file outlining the scope and changes made in this commit.
