/**
 * Reconciles every Modules\Core\Payment\Models\PaymentMethod row's `driver`
 * column against PaymentDriverRegistry — the registry only knows "which
 * driver classes exist THIS deploy," and only at the moment something
 * calls resolve(); nothing else notices a driver disappearing (a package
 * removed, a custom Registry::register() call deleted) on its own. Meant
 * to run unconditionally on every container start/deploy (alongside
 * `migrate`), not on a schedule — "did the set of registered drivers
 * change" is a deploy-time event, cheap enough to check every single time
 * regardless of whether anything actually changed. See docs/payments.md.
 *
 * Sets/clears `driver_missing_at` — deliberately NOT the `enabled` column,
 * so an admin's own manual toggle is never confused with "the driver
 * vanished," and a driver that comes back in a later deploy auto-clears
 * this with no admin action needed.
