Subject: [PATCH] feat(bedrock_mantle): add xai.grok-4.3 to model cost map for
 SigV4 auth (#31916)

Register bedrock_mantle/xai.grok-4.3 with /v1/responses in
supported_endpoints so the data-driven gate routes it through
BedrockMantleResponsesAPIConfig (which inherits SigV4 signing via
BedrockMantleAuthMixin). Without this entry the model falls through to
None and forces bearer-token-only auth.

Pricing sourced from AWS Bedrock pricing page.

Closes #31196
