✅ test(model-runtime): classify ollamacloud "context window exceeds limit" as ExceededContextWindow (#15411)

* 🐛 fix(model-runtime): classify ollamacloud "context window exceeds limit" as ExceededContextWindow

ollamacloud surfaces context-window overflow as a generic 400 the upstream
labels ProviderBizError. Document the ollamacloud provenance on the existing
`context window exceeds` ECW pattern and add a regression test asserting the
message wins over the 400 / ProviderBizError catch-alls.

Fixes LOBE-9913
