Add a shared `performance-metrics` feature module for perf metric APIs, DTOs, and formatting, then surface global 24h model performance on the dashboard with cards and a top-model table.
Reuse the shared metrics module from pricing model details, remove duplicated perf API/formatting code from pricing, and add localized labels for the new dashboard performance UI.
Add a batched performance summary API for model square cards and show compact latency, throughput, and status metrics without increasing card size. Also fix OTP verification form submission.
