[chain-pr 12/12] Migrate e2e and performance test apps and scenarios to v7 APIs

[johnHackworth]

This PR is part of a chain split from #0 v7 by chain-pr.

Changes

Update test apps (microfrontend, base-extension, performance harness) to use vitalKey-based startDurationVital and crossorigin script loading. Migrate e2e framework (createTest withMockClock, intakeProxyMiddleware batchTime), session/recorder/shadow DOM/actions/resources/views/vitals/tracing/sessions/multi-tab/sessionStore/trackingConsent/init/logs/telemetry scenarios to the v7 defaults (Change records, MASK_USER_INPUT, propagateTraceBaggage default, no PCI/usePciIntake/forwardErrorsToLogs→console.error, no FID, async session). Bump browser test versions in unit browsers.conf.
