Till JS ed76f53b00 feat(sync): Phase 2 — server-side billing gate, cron charging, email notifications ... Server-side gating (mana-sync Go): - New billing.Checker with 5-minute cache per user - Middleware wraps POST/GET /sync/{appId} endpoints - Returns 402 Payment Required when sync subscription inactive - Fail-open: if mana-credits is unreachable, sync is allowed - Config: MANA_CREDITS_URL + MANA_SERVICE_KEY env vars Recurring charge cron (mana-credits): - Hourly setInterval checks for due sync subscriptions - Calls chargeRecurring() which debits credits and advances nextChargeAt - On insufficient credits: pauses subscription, sends email via mana-notify Email notifications: - Sends "Cloud Sync pausiert" email via mana-notify when subscription paused - Uses POST /api/v1/notifications/send with X-Service-Key auth Client-side 402 handling: - sync.ts detects 402 from push/pull, fires onBillingRequired callback - Layout wires callback to reload syncBilling store → shows pause banner Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		2026-04-10 22:28:57 +02:00
