The autoRouterPresets mock imported litellm/proxy/public_endpoints/autorouter_presets.json
as a module. That path sits outside ui/litellm-dashboard, the only directory the UI
Dockerfile copies, so `next build` type-checking inside the image failed with
"Cannot find module" and the ui-image job went red on every PR that touched an
image-scan path. Read the file with fs at runtime instead; vitest still derives
expectations from the real bundled catalog.

The dashboard's template picker imported autorouter_presets.json at build time, so every
catalog change needed a dashboard rebuild and artifacts refresh. The catalog now lives in
litellm/proxy/public_endpoints/ and GET /public/autorouter_presets serves it, fetching
litellm.autorouter_presets_url (GitHub raw on main, 1h in-process cache, bundled fallback)
so a merged catalog change propagates to running proxies like the model cost map does.
The dashboard fetches it at runtime via useAutoRouterPresets and keeps no local copy.
