feat: expose autocomplete scores and add frontend e2e smoke CI

[igorsatsyuk]

Что сделано\n- �utocomplete-service: AutocompleteQueryService теперь читает Redis ZSET через

everseRangeWithScores и возвращает реальный score в AutocompleteEntry.\n- Обновлены тесты AutocompleteQueryServiceTest и AutocompleteServiceRedisIT (включая строгую JSON-проверку контракта).\n- rontend: добавлена клиентская сортировка подсказок по score (убывание) + unit-тест на порядок.\n- Добавлен постоянный smoke e2e тест rontend/scripts/e2e-smoke.js и команда
pm run test:e2e-smoke.\n- CI: добавлен отдельный job rontend-e2e-smoke (docker compose up +
pm run test:e2e-smoke).\n- Telegram summary: в .github/scripts/compose_telegram_message.py добавлен статус rontend-e2e-smoke.\n- Документация обновлена в README.md и CONTRIBUTING.md.\n\n## Проверки локально\n- mvn -Dtest=AutocompleteQueryServiceTest test (�utocomplete-service)\n- mvn -Dit.test=AutocompleteServiceRedisIT verify (�utocomplete-service)\n-
pm run test:ci -- --include src/app/services/autocomplete.service.spec.ts (rontend)\n-
pm run test:ci (rontend)\n-
pm run test:e2e-smoke (rontend, при поднятом compose)\n\n## Зачем\n- Пробросить score до API-контракта и использовать его на клиенте для детерминированного порядка подсказок.\n- Зафиксировать end-to-end поведение отдельным smoke job в CI и отразить его результат в Telegram уведомлении.

Pull request overview

This PR exposes Redis ZSET scores all the way to the autocomplete API contract, uses those scores on the frontend to enforce deterministic ordering, and adds a Playwright-based frontend E2E smoke test with a dedicated GitHub Actions job and Telegram reporting.

Changes:

• autocomplete-service: switch to reading ZSET entries via reverseRangeWithScores and return real score values; update unit/integration tests to validate the contract.
• frontend: client-side sort by score (desc) with a unit test verifying order.
• CI/docs: add frontend/scripts/e2e-smoke.js, npm run test:e2e-smoke, a new frontend-e2e-smoke workflow job, Telegram summary integration, and documentation updates.
