Add a Bun script to apply and normalize AGPL copyright headers across the default frontend source files.
The script keeps headers idempotent, upgrades existing headers to the 2023-2026 QuantumNous range, and is exposed through `bun run copyright` for future maintenance.
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.
