fix(reports): route 77xx nedskrivningar to the anläggningstillgångar RR line (#1644)

* fix(reports): route 77xx nedskrivningar to the anläggningstillgångar RR line per BAS kopplingstabell

The whole 7700-7799 block was mapped to "Nedskrivningar av
omsättningstillgångar utöver normala nedskrivningar" in both the K2
årsredovisning mapper (preview + filed iXBRL) and the INK2R engine.
Per the official BAS kopplingstabell (INK2R 3.9/3.10), only 774x and
779x belong there; 7700-7739 and 7750-7789 (nedskrivningar of
anläggningstillgångar and their återföringar) belong on "Av- och
nedskrivningar av materiella och immateriella anläggningstillgångar"
together with 78xx. Totals were unaffected; the line split was wrong
for four BAS account groups.

Reported via gnubok_feedback 2026-07-07 (K2 side). The stale
swedish-sru-filing reference row carried the same error and is
corrected to match.
