Pull request overview

This PR removes the legacy Selenium/PyPOM-based functional test framework from Bedrock (page objects, Selenium-specific fixtures, and CI/grid wiring) and simplifies the integration-test workflows to run only the remaining HTTP-based pytest suites (plus Playwright separately).

Note: This review was performed following the repository’s custom Copilot instructions (including checking AGENTS.md guidance and verifying repository-wide references via search).

Changes:

• Deleted Selenium/PyPOM page objects and the one remaining Selenium navigation test.
• Removed Selenium-related pytest fixtures/markers and pruned Selenium/PyPOM dependencies from dev requirements.
• Simplified integration test scripts and GitHub Actions workflows by removing Selenium Grid / SauceLabs configuration.

r+wc => let's hold off on merge until we have a successful integration test run

The vendor-local folder looks like an unrelated change. Otherwise, all looks good to me.

Integration tests failure: https://github.com/mozilla/bedrock/actions/runs/27763378024/job/82143415537

The integration tests have passed: https://github.com/mozilla/bedrock/actions/runs/27839980565/job/82396622227. The playwright tests failures seem to be related to the VPN env discussed here: https://mozilla.slack.com/archives/C0960JM31PE/p1781721519443169
