1000_novels: drop the Wolne Lektury footer path, pin the screen CSV (888 -> 887 texts)

Maintainer decision: a Wolne Lektury public-domain footer no longer keeps a
row. 1000_novels_0734 (translator "A.L.", not identified) fails closed as
unresolved. Screen totals: pd_by_term 887, in_copyright 18, unresolved 95.

clean_1000_novels.py pins the screen CSV by SHA-256 (7fefc75f...) and exits on
a mismatch; the same value is in license-evidence.json, and a contract test
checks that the two match.
