🧹 chore: Remove Deprecated Gemini 2.0 Models & Fix Mistral-Large-3 Context Window (#12453)

Browse source 
* chore: remove deprecated Gemini 2.0 models from default models list

Remove gemini-2.0-flash-001 and gemini-2.0-flash-lite from the Google
default models array, as they have been deprecated by Google.

Closes #12444

* fix: add mistral-large-3 max context tokens (256k)

Add mistral-large-3 with 255000 max context tokens to the mistralModels
map. Without this entry, the model falls back to the generic
mistral-large key (131k), causing context window errors when using
tools with Azure AI Foundry deployments.

Closes #12429

* test: add mistral-large-3 token resolution tests and fix key ordering

Add test coverage for mistral-large-3 context token resolution,
verifying exact match, suffixed variants, and longest-match precedence
over the generic mistral-large key. Reorder the mistral-large-3 entry
after mistral-large to follow the file's documented convention of
listing newer models last for reverse-scan performance.
