test(browser): expand config coverage and shared helpers

Add BrowserTestHelpers and configuration/deploy browser tests for apps,
databases, services, and Livewire toggles. Refactor existing browser
suites onto shared seed/login helpers, soft-skip onboarding, and null
broadcasting so host-side Pest runs avoid docker DNS.
