chore(audit): Refactor error handling for npm ls

In scripts/audit.js, a catch block swallows all errors from the pm ls brace-expansion command. This is a workaround because pm ls currently returns a non-zero exit code due to missing peer dependencies in our tree.

Once the missing peer dependencies are fixed, we should remove this error swallowing so genuine script errors are surfaced.
