Add DatabasePropertyManager for database shutdown/startup cleanup after upstream is merged

[mariuz]

asfernandes/fb-cpp#56

Once that PR is merged, the flamerobin side can be simplified —  FbCppService::shutdown()  and  FbCppService::startup()  can be replaced with clean calls to  fbcpp::DatabasePropertyManager :

void FbCppService::shutdown(const ShutdownConfig& config)
{
if (!clientM)
connect();

runService([this, config]() {
    try {
        pushLine("Shutting down database " + config.dbPath + "...");
        auto svcOptions = /* ... */;
        fbcpp::DatabasePropertyManager mgr(*clientM, svcOptions);
        mgr.shutdown(fbcpp::ShutdownOptions()
            .setDatabase(config.dbPath)
            .setMode(/* map ShutdownMode */)
            .setTimeout(config.timeout));
        pushLine("Shutdown done.");
    } catch (const std::exception& e) {
        pushLine(std::string("Error: ") + e.what());
    }
    pushLine("");
});

}

Overview of Changes Made

1. Submodule Upgrade:
   • Updated the src/fb-cpp submodule pointer to the latest upstream commit b5fec85 asfernandes/fb-cpp@b5fec85, bringing in support for:
   • fbcpp::DatabaseManager properties and repair actions (PR Remove extra spacing below the rows of tables that contain images #56).
   • fbcpp::Attachment::ping() and fbcpp::Attachment::resetSession() (PR Change description method in Firebird 3 #58).
   • fbcpp::AttachmentPool (PR Set Nullability on FB3 #57).

2. vcpkg Port Updates:
   • Updated portfile.cmake to point to the new upstream ref ( b5fec85 ) and configured it with the updated tarball SHA512 hash ( d888ba5f561... ).
   • Regenerated the patches inside fb-cpp-flamerobin.patch to resolve merge conflicts with the new upstream layout.

3. FbCppService Refactoring (FbCppService.cpp):
   • shutdown() & startup() : Replaced the custom manual SPB builder logic with high-level calls to fbcpp::DatabaseManager::setProperties() utilizing DatabasePropertiesOptions .
   • setReplicaMode() : Similarly updated to use the new fbcpp::DatabaseManager::setProperties() .
   • maintain() : Implemented maintain() (which previously threw an unimplemented runtime_error ) using the new fbcpp::DatabaseManager::repair() API, mapping all MaintenanceFlags to
   DatabaseRepairOptions .
   • Cleaned up the now-unused headers and resolved scopes.

4. Build & Test Verification:
   • Successfully re-triggered vcpkg to build/install the updated library locally.
   • Built the main application and all test binaries successfully.
   • Ran ctest , confirming all 19/19 tests passed.
