Fio's transparent page now serves recent rows as DD.MM.YY while older
rows stay DD.MM.YYYY. parse_czech_date only knew the 4-digit form so
every recent transfer was silently dropped — make sync-2026 reported
zero new transactions. Adds %d.%m.%y and %d/%m/%y to the format list,
mirroring the Go-side fix from 2026-05-07.
Also adds a Python analog of make go-sync-debug:
- --dry-run skips header write / append / sort and prints "would …" lines
- --print-fio-table prints aligned per-txn table with NEW/DUP status
- make sync-debug [DAYS=N] wrapper (default DAYS=30)
- always-on stderr diagnostics in fio_utils: which fetcher was chosen
(with FIO_API_TOKEN-unset lag warning) + raw-vs-filtered counts, so
this class of "scraper drops everything" bug surfaces immediately.
