The original fix only whitelisted agefield, condition_field, and
substitution_field at the point they're saved in
tools/automatic_item_modification_by_age.pl, leaving the actual
consumer of the stored syspref, C4::Items::ToggleNewStatus, trusting
agefield and substitution field unchecked. agefield is spliced
directly into raw SQL (TO_DAYS($agefield)) and so can't be
parameterized like an ordinary value; substitution field reaches a
dynamic method call ($item->$field($value)). Any future or
alternate writer of the automatic_item_modification_by_age_configuration
syspref would have reopened both holes without touching the form at
all.
This adds the same allow-list validation directly in ToggleNewStatus
(falling back to the safe default agefield, or skipping the
substitution/condition, exactly as before for missing values), shares
the age-field allow-list between the two files via a new
GetAutomaticItemModificationAgeFields() in C4::Items so it can't drift
between them, and logs rejected values via Koha::Logger instead of
silently discarding them so tampering leaves an audit trail.
