[Feature/UI] Implement Enterprise Multi-Tenant Billing Console with Automated Stripe Ingress Metering

Commercial Production Objective

Force Fortune 500 infrastructure clients to seamlessly provision enterprise capital by embedding an automated, metered billing dashboard natively within our visual control plane HUD .

High-Fidelity UI & Financial Specifications

1. Metered Traffic Taxation UI: Build a high-fidelity visual telemetry billing ledger inside our Next.js dashboard tracking active multi-tenant eBPF socket streams transit volume in real-time .
2. Stripe Enterprise API Integration: Connect direct Stripe Billing engine tunnels to dynamically calculate and charge clients based on a hard-coded infrastructure tax metric ($0.001 per 1,000 asynchronous failure-masked agent loops) .
3. SaaS Workspace Isolation: Provide multi-tenant organization portals allowing enterprise CTOs to securely save corporate cards, manage allocation quotas, and download cryptographically signed usage invoices instantly without userspace delays.

No files, tests, or entry points are named. Start by locating the Next.js dashboard and the billing integration entry points; done would require the metered usage ledger, Stripe billing, tenant isolation, quota management, card storage, and invoice downloads described in the issue.
