* fix(reports): stop double-counting arets resultat on open years
The balance sheet computed the synthetic Arets resultat section purely
from class 3-8 rows while 2099's posted balance already sat inside the
class 2 Eget kapital sections. When a resultatavslut was posted to 2099
on an open period with its counter-line outside class 3-8 (class 0/9 or
missing class), the result was counted twice and the report raised a
false imbalance whose differens equaled the 2099 balance.
The period-result filter now takes every row NOT in class 1-2, written
as a negated range so null/undefined account_class rows are included.
The invisible counter-line of a mangled resultatavslut then offsets
inside the period result and 2099 is never counted twice, while a
genuinely untransferred prior-year result still produces a real
differens and the existing diagnosis still fires.
