fix(lotw): strip STATE ' // Name' suffix for award stats

LoTW returns STATE as 'CODE // Name' (verified with a real report 2026-09),
e.g. 'GD // Guangdong' (China), '34 // Tottori-ken' (Japan), 'CA // California'
(US). The award calculator matched on the bare CODE, so every mainland China
province (WAPC), all Japan prefectures (WAJA) and US states (WAS) failed —
WAPC only showed HK/MO/TW (entity branch, no STATE needed) and WAJA was empty.

Normalize STATE once at parse time: strip the ' // Name' suffix so the stored
GridQso.state is the clean code consumed by persistence and AwardCalculator.
Add a test covering China/Japan/US formats.
