refactor: consolidate business logic in FmcdCore and fix balance calc… #10
Conversation
…ulation - Fix zero balance bug by using client.get_balance() instead of only counting mint notes - Remove duplicate implementations between FmcdCore and API layers - Implement PaymentInfoResolver trait pattern for LNURL handling without coupling core to web protocols - Move all business logic (get_info, join_federation, create_invoice, pay_invoice) to FmcdCore - Make API layer a thin wrapper that delegates to FmcdCore methods - Add proper error handling and context propagation throughout

Pull Request Overview
This PR consolidates business logic into the FmcdCore module and fixes a critical balance calculation bug. The refactoring implements a clear separation between the core business logic and the API layer, making the API a thin wrapper that delegates to the core.
- Fix zero balance bug by using
client.get_balance()instead of only counting mint notes - Consolidate all business logic (get_info, join_federation, create_invoice, pay_invoice, withdrawal, deposit) into
FmcdCore - Implement

Cloning the entire MultiMint for federation registration is expensive. Consider if this clone is necessary or if the operation can be performed on the Arc directly.

Parsing a Bolt11Invoice twice (once here for validation, then again in the core) is inefficient. Consider returning the parsed invoice or restructuring to avoid duplicate parsing.

The balance fix uses client.get_balance() which includes all modules, but the response structure suggests it should only represent mint module data based on the comments about 'ecash notes'. This could be misleading to API consumers who expect only mint balance.
