Subject: [PATCH] fix(explorer): exclude approval events from Total column
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ERC20 Approval events were being counted as value transfers in the
Total column, inflating the displayed amount. For example, a tx with
approve(1 USDC) + deposit(1 USDC) showed $2 instead of $1.

Approvals grant spending permission — no tokens are moved — so they
should not contribute to the total value sum.
