zh quests: translate.lua builder + first 100 quest strings

40250 quests say gameforge.<quest>.<key>, loaded by game from
share/locale/<locale>/translate.lua at start. build_zh_translate_lua.py
lays the reviewed data/zh_40250/quest_translate_zh.tsv over the English
file line by line (nested tables kept), re-wraps at the quest window
width, and writes GBK with 0x5C trail bytes doubled. Deployed on 203;
blacksmith dialog shows Chinese.
