fix(tests): Catch the missed assertion shapes and revert init.js noise

- Update tanstack-router (solid/react/vue) e2e tests: drop measurements
  expectations, swap to `browser.web_vital.{ttfb,fp,fcp}.value` attribute
  checks on the pageload trace data. LCP intentionally not asserted (fires at
  pagehide, lost in static mode).
- Update connection-rtt browser-integration test to look at
  `network.connection.rtt` attribute instead of the removed
  `measurements['connection.rtt']`.
- Update react-create-{browser,hash}-router e2e transactions tests to use the
  new OTel-style attribute names (`device.memory.estimated_capacity`,
  `network.connection.effective_type`, `device.processor_count`,
  `browser.performance.time_origin`, `browser.performance.navigation.activation_start`).
  Drop legacy `lcp.*` data assertions.
- Delete browser-integration suites for `experimental: { standalone: true }`
  (`public-api/startSpan/standalone`, `standalone-mixed-transaction`). They
  exercised a removed code path.
- Revert the prior `webVitalsIntegration({ disable: ['inp'] })` additions to
  init.js files (long-tasks/animation-frame, linked-traces). The `enableInp`
  removal alone is enough; auto-registered web vitals don't affect those
  navigation/long-task tests.
