Migrate e2e tests from Cypress to Playwright

- Replace deprecated @grafana/e2e (Cypress) with @grafana/plugin-e2e (Playwright)
- Add full e2e scenario: ingest logs into Quickwit, create datasource via UI,
  verify log explorer returns hits, cleanup
- Use unique RUN_ID per test run for isolation
- Add Quickwit version matrix (edge) to CI
- Add job timeout (15min) and health checks for both Grafana and Quickwit
- Parameterize Quickwit Docker image version via QUICKWIT_VERSION env var
- Bump default Grafana to 12.4.0 (required for react/jsx-runtime external)
