Varbase 10.1.2 Patch release for existing Varbase 10.1.x (Drupal ~11.4) sites. Moves the Automated Functional Testing suites onto Varbase E2E (@vardot/varbase-e2e ^2, Playwright + Cucumber-js), clears the PHPStan findings raised by the updated analyzers, and pins every cross-dependency to its released version.
