* fix(minimax): use dedicated image generation endpoint
MiniMax image generation uses a dedicated API endpoint
(api.minimax.io/v1/image_generation) that is separate from the
text/chat API endpoint (api.minimax.io/anthropic).
Previously, the resolveMinimaxImageBaseUrl function would extract
the origin from the provider's configured baseUrl. If a user had
configured their baseUrl to the chat endpoint (e.g.,
api.minimax.chat/anthropic), the image generation would incorrectly
use that endpoint, resulting in "invalid api key" errors.
This fix always uses the dedicated image generation endpoint,
ignoring the provider's baseUrl configuration for image generation.
Fixes#61149
* fix(minimax): support CN endpoint for image generation
Respect MINIMAX_API_HOST environment variable to determine whether
to use the global (api.minimax.io) or CN (api.minimaxi.com) endpoint
for image generation.
This ensures that CN users who configure MINIMAX_API_HOST to use
api.minimaxi.com will continue to use the CN endpoint for image
generation, while global users continue to use api.minimax.io.
The original bug was caused by the code extracting the origin from
the provider's configured baseUrl, which could be set to incorrect
endpoints like api.minimax.chat. This fix uses the dedicated image
generation endpoints instead.
Fixes#61149
* fix(minimax): infer CN endpoint from provider config when env is unset
When MINIMAX_API_HOST is not set, fall back to checking the provider's
configured baseUrl to determine whether to use the CN or global image
endpoint. This ensures CN users who went through onboarding (which sets
models.providers.minimax.baseUrl to https://api.minimaxi.com/anthropic)
are correctly routed to the CN image endpoint.
The isMinimaxCnHost check ensures we only use the baseUrl origin for
CN detection - invalid endpoints like api.minimax.chat would not match
minimaxi.com and would correctly fall through to the global default.
Fixes#61149
