"""
YUSEN db-aware routing patch for Odoo 18.

Odoo 18 resolves the database from the Host header via dbfilter. The
yt.pengyuthon.cn front-end proxies /game/ and /yt_world/ requests to Odoo
with Host "game.pengyuthon.cn" (a virtual host), which does NOT match the
fixed dbfilter list. As a result those requests fall through to the
database-free routing map and return 404.

This patch forces the correct database for path-prefixed game routes so the
real controllers (game_base) are reachable.
