SURYA READS ITALIAN AGAIN. Measured on the live install, the same synthetic page
that scored 29 markers all morning:

    MARKERS : 0    (29 baseline)
    ACCENTS : AEEIOUaeeiou (all twelve)
    La societa` ha facolta` di piu` attivita`: percio` e` cosi` che l'unita`
    perche' gia` oltre.

...but it reported `accents_repaired: null` while visibly having fixed the page,
because _page_from_dict carried `unreadable_trace` across the worker boundary and
never carried `accents_repaired`. The fix worked; only its receipt was dropped.

That matters more than a missing field: the text is no longer byte-for-byte what
the server sent, and a caller comparing the two has no way to know why. A silent
fix is nearly as bad as a silent corruption.

tests: +2 (47 in test_ocr_accent_repair.py) for the receipt crossing the boundary
and for staying absent when nothing was repaired.
