Registering a module in access.GoAutoModules() does not make its page
reachable on an existing database. sys_menu rows are written by the
versioned migration that first created them, and that version is already
recorded in sys_migration everywhere — it never runs again. Startup only
reconciles the casbin API matrix, not menus.
So on a fresh database the page appeared and on every real one it did not:
the table, the API and the route were all present with no way to navigate
there. This adds a migration that upserts the entry under 采采管理 beside
「SYB 店铺」 and binds it to both 管理员 and 采购员.
Verified by deleting the row from an already-migrated database and
re-running migrate: 新执行 1 个，跳过 42 个, row restored with both roles.
