Correct documentation that no longer matched the code:

• README (en/ru): the production stack is served on ports 80/443 via nginx, not 8082; provider example used a non-existent --public-url flag; removed links to missing "troubleshooting" and "recommended hardware" anchors; license line said "All Rights Reserved" while the project is Apache-2.0; fixed a broken bold marker and stale "2025" roadmap wording; Node.js requirement now matches CI and Dockerfile.
• CONTRIBUTING: there is no npm test script; point to lint and typecheck, which CI runs.
• doc/TESTING: test/ui -> test/e2e, --exit-code-from flag typo, base URL semantics for the API tests.
• mongo.md and docker-compose docs: correct MongoDB version notes, add the required --env-file, fix the non-existent devicehub-processor001 service name, and document that services with container_name cannot be scaled as written.
• Autotests and Appium how-tos: endpoints are GET/DELETE /api/v1/autotests (not /autotests/captureDevices|freeDevices), and the Python client base_url must include /api/v1.
• API.md: consistent heading for the remoteConnect DELETE endpoint.
• iOS device doc: correct helper script path, drop unsupported ios-provider flags, and point to npm run setup-wda.
• units-describe: fix "prooxy" -> "poorxy" and stray words.
• group-roles: rewrite to match hasGroupEditPermission and the moderator/owner logic in the code.
• Python client README: replace template placeholders with DeviceHub examples.
