Wazuh-engine: Fetch policy from indexer connector

[juliancnn]

Closes #33519

Description

Introduces changes to the Wazuh engine to fetch policies from the indexer connector. It includes updates to the codebase for handling policy retrieval, hash checking, and existence verification.

Proposed Changes

• WIC dded new methods in the IWIndexerConnector interface for policy management.
• WIC Implemented the getPolicy, getPolicyHash, and existsPolicy methods in the WIndexerConnector class, to query on wazuh-indexer.
• WIC: Introduced the PolicyResources structure to encapsulate policy-related data.
• IndexerConnectorAsyncImp: Added search and Point In Time features
• .devContainer: Modified Docker and development container configurations for testing and integration

Results and Evidence

No new test or final user feature added, but is posibble check adding this code and debugging:

                if (indexerConnector->existsPolicy("free"))
                {
                    LOG_INFO("Indexer Connector initialized. 'free' policy exists.");
                }
                LOG_INFO("Policy 'free' hash {}", indexerConnector->getPolicyHash("free"));
                auto t = indexerConnector->getPolicy("free");

                // Print sizes of retrieved resources
                LOG_INFO("Policy 'free' resources - KVDBs: {}, Decoders: {}, Integration Decoders: {}",
                         t.kvdbs.size(), t.decoders.size(), t.integration.size());

                LOG_INFO("Policy 'test2' exists: {}", indexerConnector->existsPolicy("test2") ? "true" : "false");
