fix(openai): resolve Anthropic compat mapping from normalized model

Browse Source 
Anthropic compat requests normalize reasoning suffixes before forwarding, but the account mapping step was still using the raw request model. Resolve billing and upstream models from the normalized compat model so explicit account mappings win over fallback defaults.

Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent)
