Add: receipt details to ReceiptInterface

[alikhani97]

We have this issue where we don't have access to the receipt details right after verifying payment!

Motivation for the Change

1. Standardization: These additions align the ReceiptInterface with the Receipt implementation, ensuring all details are accessible through the defined interface methods.
2. Flexibility: Provides a built-in way for users to retrieve metadata stored in detail() without requiring dedicated getters for each specific key.
3. Code Consistency: Brings parity between the concrete Receipt class (which uses HasDetail) and its contract, making it clear that details and metadata are part of the core functionality.
4. Improved Usability: Users can now access and manipulate transaction metadata more easily through methods that adhere to the interface, improving the developer experience.
