## PR-Codex overview
This PR focuses on improving the code by replacing `Number.parseInt` with `Number` for checking if a value is an integer across multiple files, enhancing readability and consistency.

### Detailed summary
- In `TokenSelector.tsx`, changed `Number.parseInt(searchValue)` to `Number(searchValue)`.
- In `single-network-selector.tsx`, modified the same integer check.
- In `ConfigureCustomChain.tsx`, updated integer check for `chainSlug`.
- In `NetworkSelectors.tsx`, replaced the integer check similarly.
