feat: [BBND-1329] sdk new methods

[rubenbermejo3]

Description

Implement new SDK methods for bond management following the CQRS pattern (Commands & Queries) with full Hexagonal Architecture compliance.

This PR adds comprehensive SDK support for Fixed Rate Bonds, KPI-Linked Rate Bonds, Interest Rate Management, KPI Data Tracking, Coupon Ordered Lists, and Scheduled Coupon Listings. Each feature follows the established architecture: Request DTO, Command/Query + Handler, Port/In Facet, Port/Out Adapters (RPC + Hedera), Domain Models, DI registration, and unit/integration tests.

New Commands (6):

• CreateBondFixedRate - Create bonds with fixed interest rates
• CreateBondKpiLinkedRate - Create bonds with KPI-linked dynamic rates
• SetRate - Set fixed interest rate for a bond security
• SetInterestRate - Configure full interest rate parameters (max/base/min rates, start period, penalties)
• SetImpactData - Configure KPI impact parameters (deviation caps/floors, baseline, adjustment precision)
• AddKpiData - Submit KPI data for KPI-linked bonds

New Queries (10):

• GetRate / GetInterestRate / GetImpactData - Retrieve interest rate configurations
• GetLatestKpiData / GetMinDate / IsCheckPointDate - KPI data and checkpoint validation
• GetCouponsOrderedList / GetCouponsOrderedListTotal / GetCouponFromOrderedListAt - Paginated coupon queries
• ScheduledCouponListingCount / GetScheduledCouponListing - Scheduled coupon task queries

New Domain Models: BondFixedRateDetails, BondKpiLinkedRateDetails, ImpactData, InterestRate, BondFixedRateDetailsData, BondKpiLinkedRateDetailsData, FactorySecurityToken, InvalidNegativeRate

New Port/In Facets: FixedRate, KpiLinkedRate, Kpis, ScheduledCouponListing

New Request DTOs: 17 new request classes with validation

Adapter Extensions: RPCTransactionAdapter, HederaTransactionAdapter, RPCQueryAdapter, and TransactionAdapter extended with all new transaction/query methods

⚠️ Minor Observations

1. Missing Injectable Modules

The injectable structure could be improved by creating dedicated modules for:

• interestRates/ injectable module
• scheduledTasks/ injectable module

Currently, interest rate handlers are included in InjectableBond.ts, which is functional but could be better organized.

2. Query Adapter Implementation

Only RPC query adapters are required (per specifications), and this appears to be correctly implemented.
