feature(ampcode): Improves AMP model mapping with alias support

Enhances the AMP model mapping functionality to support fallback mechanisms using .

This change allows the system to attempt alternative models (aliases) if the primary mapped model fails due to issues like quota exhaustion. It updates the model mapper to load and utilize the  configuration, enabling provider lookup via aliases. It also introduces context keys to pass fallback model names between handlers.

Additionally, this change introduces a fix to prevent ReverseProxy from panicking by swallowing ErrAbortHandler panics.
