T10: Monitoring, Performance, Documentation & Environment Config — 38 tests, ruff clean, docs OK

- Extended health endpoint: DB+Redis+Storage+Worker checks with degraded status - Prometheus metrics endpoint: admin-only, text/plain format - Metrics: http_requests_total, db_pool_connections, arq_jobs_total - Structured JSON logging (structlog): timestamp, level, method, path, status, duration_ms, tenant_id - Performance: page_size max 100 enforced (422), streaming CSV export (StreamingResponse) - Scripts: seed_perf_data.py, check_indexes.py - Docs: admin-guide.md (Deploy, Backup, Restore, Env-Vars, Troubleshooting), api-overview.md - README updated: prod setup, API section, env profiles, admin-guide link - .env.example: added SECRET_KEY, STORAGE_PATH, SMTP_* vars - 38 new tests, full regression 564/564 pass (0 failures) - Ruff: all checks passed
