feat: Integrate Bolt11Invoice wrapper

- Update type aliases for Bolt11Invoice based on feature flags
- Add maybe_convert_invoice and maybe_wrap_invoice functions for type conversion
- Update payment code to work with the new wrapper type
- Modify liquidity and unified_qr modules to handle wrapped invoices
- Skip doctest execution when uniffi feature is enabled to avoid conflicting Bolt11Invoice type assumptions
