Pre-merge author checklist

I've completed the PR template to the best of my ability
I’ve included tests if applicable
I’ve documented my code using JSDoc format if applicable

Pre-merge reviewer checklist

I've manually tested the PR (e.g. pull and build branch, run the app, test code being changed).
I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

Note

Low Risk
Small defensive change in token list/image resolution; main risk is minor regressions in native-asset icon fallback/selection on edge networks.

Overview
Improves resilience when building native-token entries in useTokensWithFiltering for multichain balances.

The hook now uses getNativeAssetForChainIdSafe and guards getAssetImageUrl with a try/catch, so unsupported/custom EVM chain IDs (including decimal-string chainIds) don’t throw during native token image resolution and instead fall back to available icons/undefined.
