fix: blockscout balances

[kvhnuke]

Summary by CodeRabbit

• Bug Fixes

  • Fixed API URL construction for Blockscout-backed networks so native and ERC‑20 balances load more reliably; users should see fewer failed requests, more consistent balances, and reduced loading/error states (including after network switches).

• Chores

  • Extension package version bumped to 2.13.1 (no user-facing behavior changes).

Walkthrough

Updated URL construction in the Blockscout asset handler to strip any trailing or embedded api? from the base endpoint via NetworkEndpoints[chain].replace('api?', '') before building native and ERC‑20 token balance API URLs. Fetching, validation, mapping to TokenBalance, and error handling remain unchanged.

Changes

Cohort / File(s)	Summary
Blockscout balance URL construction packages/extension/src/providers/ethereum/libs/assets-handlers/blockscout.ts	Adjusts native and token balance endpoint construction to use NetworkEndpoints[chain].replace('api?', '') before appending paths. No changes to response handling, mapping, or exported signatures.
Package version bump packages/extension/package.json	Bumps @enkryptcom/extension version from 2.13.0 to 2.13.1. No functional code changes.

31-32: Consider URL utility for more robust endpoint handling.

The current string replace approach works for the immediate fix, but consider using the URL API or a dedicated URL utility for more robust endpoint manipulation in the future. This would handle edge cases like:

• Preserving legitimate query parameters
• Handling trailing slashes consistently
• Case-insensitive matching if needed

For example, using the URL API:

const buildBlockscoutUrl = (base: string, path: string): string => {
  // Remove 'api?' if present (case-insensitive)
  const cleanBase = base.replace(/api\?/i, '');
  // Ensure no double slashes when joining
  const normalizedBase = cleanBase.endsWith('/') ? cleanBase.slice(0, -1) : cleanBase;
  return `${normalizedBase}/${path}`;
};

const nativeTokenUrl = buildBlockscoutUrl(
  NetworkEndpoints[chain], 
  `api/v2/addresses/${encodedAddress}`
);
const tokenBalancesUrl = buildBlockscoutUrl(
  NetworkEndpoints[chain],
  `api/v2/addresses/${encodedAddress}/tokens?type=ERC-20`
);
