Reconcile Intents

Settle pending intents that never heard a webhook (WP-6): one-time checkouts after AGENT_MDX_RECONCILE_ONE_TIME_AGE_S (default 15 min; the same pass also runs every 5 min as reconcile_sweep_loop), subscription checkouts after 24 h. Body {dry_run} (default TRUE — pass false to apply). QA intents are skipped. With a session id: read the session from Stripe (GET only; the one write is the O-3 geo refund the replayed webhook path issues for a buyer outside the EU) — expired → expired, complete → replayed as the missed checkout.session.completed (same idempotent path as the webhook). Without one: the sessions created around the intent are listed first (_find_session_for); a match is handled like a stored session id, and only when Stripe positively has none is the intent expired with reason never_reached_stripe. Stripe unreadable → skip. Re-running is a no-op. SUBSCRIPTION intents stuck in processing for 15 min+ are recovered too (_reconcile_processing_subscription): the Subscription is read and, when active/trialing and in the platform's Stripe mode, granted through the webhook's own _apply_subscription.
