exit_tool: SP001: When any wrapped token's balanceOf batch fails inside step_b.fetchAllTokenBalances(), the error is silently discarded

[joanestebanr]

When any wrapped token's balanceOf batch fails inside step_b.fetchAllTokenBalances(), the error is silently discarded. The affected token is absent from the returned balance map, causing Step C to treat its entire LBT supply as SC-locked value. The final certificate sends the whole token supply to exitAddress rather than distributing it across individual EOA holders, excluding those holders from the certificate entirely.
