test: add full-stack Playwright integration test infrastructure

Sprint 12 Phase 2: Real integration tests with seed DB - R__seed_test_data.sql (Flyway repeatable, 7 members, strains, batches, docs, board, events) - TestResetController (profile-gated per-test DB reset) - docker-compose.test.yml (self-contained, tmpfs Postgres) - Dockerfile.playwright (v1.60.0, pre-installed deps) - 13 integration spec files, 70+ test cases (@smoke + @full) - seed-constants.ts, selectors.ts, api-client.ts test helpers
