feat: optimize client-side rendering

Memoized high-frequency components (`HrTile`, `TimerDisplay`, `SpotifyDisplay`) to prevent unnecessary re-renders.

Created fine-grained data extraction hooks (`useHrmData`, `useTimerData`, `useSpotifyData`) to provide stable data references to components.

Refactored components to use the new hooks, decoupling them from the main WebSocket state object.

Addressed linting issues in `useHrmData` hook.
