fix(cache_control): pick the chat-path dialect from the deployment's provider prefix (#45295) 
* fix(cache_control): resolve the chat-path dialect with the deployment api_base

* test(cache_control): type the chat-path resolver helpers

* fix(cache_control): pick the chat-path dialect from the deployment's provider prefix

Resolving with the deployment api_base followed the dispatch's azure_ai to
azure flip, so chat on a non-Foundry Azure host sent Anthropic cache_control
while /v1/messages, told azure_ai, sent the OpenAI breakpoint. Use the model's
provider prefix when the caller does not name a provider, so chat matches the
told path whatever AZURE_AI_API_BASE holds, and keep name-only resolution
everywhere else.

* fix(cache_control): keep litellm_proxy routing when the chat path reads the provider prefix

With USE_LITELLM_PROXY or litellm.use_litellm_proxy on, every call goes to the
upstream proxy, so the provider prefix no longer decides the cache format there
and resolution matches main. The plain OpenAI check reads the same provider
value as the hosted check, so one function no longer mixes two lookups

* fix(cache_control): resolve the chat-path dialect with the deployment api_base, as the call is routed

The hosted cache-format check now resolves the provider with the deployment's own api_base when the caller names none, the same provider the call dispatches to and the Responses path passes, so AZURE_AI_API_BASE no longer decides the chat format. The plain OpenAI check keeps main's name-only lookup.

* fix(cache_control): send acompletion fallbacks the caller's request, not the primary's hooked kwargs

acompletion handed async_completion_with_fallbacks the kwargs the cache seed and
prompt hook had already rewritten for the first model, so a Claude fallback behind
a Foundry GPT model received prompt_cache_options and got a 400. Fallbacks now get
a copy of the caller's model, messages, tools, and kwargs taken before the hooks,
as completion already does with its args.

Both cache seeds also read base_url before api_base, since completion sends the
call to base_url when both are set.

* fix(cache_control): keep the caller's tools list intact for acompletion fallbacks

The vector-store hook pops recognized file_search tools from the request's
tools list in place, so the fallback request built from the pre-hook snapshot
lost the retrieved context. Snapshot a copy of the list instead.

* fix(cache_control): skip acompletion's prompt hooks when fallbacks will run them

Each fallback attempt runs the prompt hooks for its own model, so running them
first in the outer call only cost a vector-store search whose result the
hand-off threw away.

* fix(cache_control): run acompletion's prompt hooks for fallbacks and leave only the cache hook to each attempt
