The restaurant/lunch warning claimed 'Momsen är inte avdragsgill sedan
2017', which is legally backwards. The 2017 reform (Prop. 2016/17:1)
abolished the income-tax deduction for representation meals (IL 16 kap
2 §) but retained the VAT deduction on a base of up to 300 SEK per
person excl. VAT, now ML 2023:200 13 kap 24-25 §§. The old 'ML 8:9'
citation pointed at the repealed ML 1994:200.
Verified against the swedish-vat compliance skill before rewording.
Adds regression tests pinning the corrected message and legalBasis.
