fix(ancpi): parse CF numbers and solutii separately, zip by position

The nested JSON in ePay HTML breaks [^}]* regex. New approach:
find all CF.stringValues independently, find all solutii independently,
then zip them by position (they appear in same order in HTML).
This correctly maps CF number → document for batch orders.
