Description

This PR adds two new methods to the MultiMintWallet for better mint quote management:

check_mint_quote - Checks the current state of a specific mint quote by querying the mint and updating the local storage. Returns the updated MintQuote with the latest state.
wait_for_mint_quote - Waits for a mint quote to be paid (using subscriptions) and automatically mints the proofs once payment is confirmed. This provides a convenient single-operation method with configurable timeout and split target options.

Both methods are available in the core MultiMintWallet implementation and exposed through FFI bindings for use in language bindings (Swift, Kotlin, etc.).

Notes to the reviewers

The check_mint_quote implementation follows the same pattern as other quote-related methods in MultiMintWallet
The wait_for_mint_quote leverages the existing Wallet::wait_and_mint_quote method, which handles subscriptions and automatic minting
Both methods properly validate that the mint URL exists in the wallet and handle errors appropriately

Suggested CHANGELOG Updates

ADDED

MultiMintWallet::check_mint_quote - Check the state of a specific mint quote
MultiMintWallet::wait_for_mint_quote - Wait for a mint quote to be paid and automatically mint proofs
