Refactors context keys for model routing

Browse Source 
Uses centralized context keys for accessing mapped and fallback models.

This change deprecates the string-based context keys used in the AMP fallback handlers in favor of the `ctxkeys` package, promoting consistency and reducing the risk of typos.
The authentication conductor now retrieves fallback models using the shared `ctxkeys` constants.
