## PR-Codex overview
This PR focuses on improving the user interface of the `TokenInfoScreen` component in the `select-token-ui.tsx` file by enhancing loading states, adjusting layout heights, and refining token display logic.

### Detailed summary
- Removed initial loading and token not found states.
- Increased `Container` minHeight from `350px` to `450px`.
- Refactored conditional rendering for token details.
- Maintained structure for displaying token name, symbol, price, market cap, volume, and contract address.

## Summary by CodeRabbit

* **Refactor**
  * Consolidated rendering logic for the token information view to centralize pending, not-found, and content states.
  * Reorganized layout so detailed token sections render only when token data is present.
  * Adjusted minimum container height for token information screens in the bridge swap widget.

<sub>✏️ Tip: You can customize this high-level summary in your review settings.</sub>
