The 2024-era CuentaRUT cartola wraps the ABONOS O DEPOSITOS header across
three lines and splits each transaction (docno / description / amount+date)
across multiple lines, so the old same-line header+row detection found 0
transactions. Rewrote row assembly as docno-delimited blocks with tolerant
column detection (ABONOS position recovered from neighbouring lines).
Recovers 12 transactions from the backfill statement; all 2025 statements
parse identically (36/5/36/12/36/29/2/5 unchanged). Backfill now 2375 txns.
