 * The installed OZ 5.x upgradeable package re-exports the non-upgradeable UUPS
 * contract and no longer includes `__UUPSUpgradeable_init()`. Several existing
 * contracts in this repo still call that hook during initialization, so we keep
 * a local wrapper that restores the expected no-op initializer surface.
