Improvement: Standardized Context Management for ERC-7715 Permissions

While implementing ERC-7715 permissions in EnvioPilot, we found that managing the permissionsContext between the initial request and the subsequent redemption (often in different parts of the app or different sessions) requires custom state management.

It would be beneficial if the smart-accounts-kit provided:

A hook or utility to persist and retrieve active permission contexts.
More granular error types for when a permission redemption fails due to limit exhaustion or expiry.
Impact: This would lower the barrier for developers to implement complex, long-running permissions and improve the overall developer experience.

Start by tracing the existing ERC-7715 permission request and redemption flow in the TypeScript kit. Clarify the intended persistence boundary across app areas or sessions and the exact distinction between limit exhaustion and expiry. The work is complete when the context utility and granular errors are agreed and validated with appropriate tests.
