feat(mirror): add contract results and logs from mirror node

[alejandroGM0]

Summary

Adds mirror-node support for reading smart contract execution data by contract ID.

This PR introduces typed APIs for:

• Contract execution results
• Contract log entries

The new APIs are available through the base mirror-node repository layer and are wired through both Spring Boot and MicroProfile integrations. The sample applications also expose simple HTTP endpoints so the behavior can be tested manually against a configured mirror node.

API Additions

Base Module

Adds two new data records:

• ContractResult for mirror-node contract execution result payloads
• ContractLog for mirror-node contract log payloads

Extends ContractRepository with:

• findResultsById(ContractId contractId)
• findResultsById(String contractId)
• findLogsById(ContractId contractId)
• findLogsById(String contractId)

Extends MirrorNodeClient with:

• queryContractResults(ContractId contractId)
• queryContractResults(String contractId)
• queryContractLogs(ContractId contractId)
• queryContractLogs(String contractId)

All methods return paged results using the existing Page<T> abstraction.

Spring Boot Integration

The Spring implementation now supports the new contract result and log queries through:

• MirrorNodeClientImpl
• MirrorNodeJsonConverterImpl
• ContractRepository

Additional tests cover repository behavior and JSON conversion for contract result/log responses.

MicroProfile Integration

The MicroProfile implementation mirrors the Spring support:

• Adds mirror-node client methods for contract results and logs
• Adds JSON conversion for the new response types
• Adds repository and converter tests

Sample Endpoints

Both sample applications now expose:

• GET /contracts/{contractId}/results
• GET /contracts/{contractId}/logs

Each endpoint returns a JSON object containing:

• contractId
• pageIndex
• size
• hasNext
• data

This makes it easy to verify the new contract result and log queries against a live mirror node.

Testing

Added coverage for:

• ContractRepositoryImpl
• Spring ContractRepositoryTest
• Spring MirrorNodeJsonConverterImplContractTest
• MicroProfile ContractRepositoryTest
• MicroProfile MirrorNodeJsonConverterImplContractTest
