fix(openai): warn when the GPT-5 reasoning effort gate drops a level under drop_params (#47761)
* fix(openai): warn when the GPT-5 reasoning effort gate drops a level under drop_params

A GPT-5 request whose reasoning_effort the model map does not enable for
that model lost the effort with no log line under drop_params. An Azure
deployment name missing from the cost map lost reasoning_effort none this
way and ran at the model's default effort. The gate now logs a warning
naming the model, the level, the map entry it checked, and the
model_info.base_model and model_info.reasoning_effort_levels fixes.

* fix(openai): warn when the Responses route or a deployment's declared levels drop a reasoning effort

The /v1/responses gate dropped a row-disabled GPT-5 effort, and reasoning for an OpenAI model without
supports_reasoning, with no log line, and the router logged a declared-level drop only at INFO. Both
Responses drops now log a WARNING and the router logs its drop at WARNING. The warning now leads with
model_info.reasoning_effort_levels, since base_model only helps a deployment named differently from
its underlying model.

* fix: warn only when a reasoning level is actually dropped, and on generic reasoning_effort drops

* fix: warn when thinking or a Bedrock Converse reasoning level is dropped, and name the router drop a reasoning level

* fix: skip the drop warning when a non-reasoning model is asked for no reasoning, and honor declared levels on Bedrock Responses

* fix: stay silent when reasoning is turned off on /v1/responses and warn on the Bedrock Responses fallback drop

* fix(reasoning): warn when any reasoning-off request is dropped and give each route only the advice it honors

A request to turn reasoning off on a model name the catalog lacks now warns on every route, since it may be a reasoning model. Chat suggests model_info.reasoning_effort_levels and, for a name with no catalog entry, model_info.base_model. OpenAI Responses suggests declared levels only where the config honors them, and Bedrock suggests neither. The Bedrock and Mantle Responses forwarding of declared levels is reverted until it can be proven live.

* fix(reasoning): suggest reasoning_effort_levels and base_model only where the route reads them

The chat gate suggested model_info.reasoning_effort_levels on routes that never pass declared levels
(github_copilot, chatgpt and other OpenAIConfig delegates) and model_info.base_model on OpenAI and
Azure AI chat, whose gate looks up the deployment name rather than base_model. /v1/responses/compact
suggested levels it never reads either.

Declared levels are now None when a caller passes none, so the advice appears only when a caller fed
them, and the base_model advice is limited to the Azure chat gate, the one that looks up base_model.

The openai row of the chat warning test now expects no base_model advice, the Responses warning test
goes through get_optional_params_responses_api the way /v1/responses and compact call it, and the Azure
direct-config test passes declared levels the way get_optional_params does. Long test lines are wrapped.

* fix: read only the built-in catalog when choosing the reasoning drop warning
