Solve SonarCloud security hotspots and bugs (#7383)

* Test: allocLockCursorToScreenInfo_withState_setsState * Merge remote-tracking branch 'origin/master' into S1-1717-sonarcloud-issues * Remove header wrappers for gmock/gtest * Convenience wrapper script for tests * Use `std::copy` instead of `strcpy` * Use `std::ranges::copy` instead of `stdcpy` * Delete dead code * Add guitests VS Code config and test wrapper * Revert "Delete dead code" This reverts commit aa40f5cd35a22b4b69acfd1876aceea053088060. * Build guitests with CMake * Run all tests * Don't use --gtest_filter for Qt tests * Undo skip for GUI tests * Coverage for `IpcClient::sendCommand` * Remove provider and proxy * Use lamda for StreamProvider to reduce boilerplate * Restore version checker tests * Remove activation souces * Tasks for current/all tests * Change command for tasks * Mock QNetworkAccessManager * Create core app to satisfy Qt assertations * Use `std::copy` instead of `std::ranges::copy` * Remove integtests * Merge guitests into unittests * Use std::string::length * Remove include (resolves to root) * Fix memory leaks * Disable sigsegv tests * Fixed formatting * Remove guitests from CI * New MainWindowTests * Passing test for MainWindowTests * Use alternative to strlen in MainWindow::checkSecureSocket * Passing test for Log::print * Fixed dtor call order * Fixed var name typo * Use proxy instead of `#define protected public` * Add args test for log * Add license ctor * Fixed log test for release * Add error log test * Init qt with -platform offscreen * Back-out initQt function * Use QT_QPA_PLATFORM * Try QT_QPA_PLATFORM=offscreen * Use more readable env node * Set QT_QPA_PLATFORM in CI and CodeQL * Remove env not needed * Modernize Log::print * Calculate the length of the format string fmt during the initial scan loop * More direct and efficient alterative to `strlen` * Fixed major maint issues in AppConfig * New clang and cmake rules * Set `max_pargs_hwrap` to 4 * Undo clang format for now * Fix missing `Setting::` * Fixed missing `m_S` on Windows * Re-add accidental dep resolution (fix later) * Fixed missing buffer position increment * Turn on errors * Fixed tests and improve error message * Fixed segfault on log refactor * Extract log time to function * Copyright date * Update ChangeLog
