fix(anymailfinder): scope block params to the operation, never default a missing charge to zero

Only the selected operation's subBlocks are forwarded to the tool, so a
company name left in another operation's field cannot leak into a lookup
through the shared company_name mapping. The four billable tools pass
credits_charged through untouched, so a response without it hits the
getCost guard instead of being recorded as free.
