fix(game_base): rebuild db-aware routing patch to fix game.pengyuthon.cn login 404

- rebuild models/ir_http.py: monkeypatch Request._get_session_and_dbname
  bind DB by URL prefix (/game/->game, /yt_world/->yt_game), guarded by db_filter
- __init__.py import ir_http to load the patch
- root cause: dbfilter=^(pengyuthon|school|test|yun|game)$, nginx proxies
  /game/ with Host:game.pengyuthon.cn; host cannot resolve db -> nodb route
  table -> /game/api/* 404, login fails
- after fix /game/api/codex and /game/api/login return 200

+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.
