chore: ruff lint auto-fix — 9 errors fixed (import sorting, unused imports)

- I001: import block sorting in main.py, routes/__init__.py, companies.py, conftest.py, check_indexes.py
- F401: unused imports removed (asyncio, UTC, datetime, AsyncSession)
- 6 ASYNC240/230 warnings remain (os.path.exists in async, open() in test) — minor, non-blocking

-## What Was Done
-- **Monitoring**: Prometheus metrics (http_requests_total, db_pool_connections, arq_jobs_total), structured JSON logging via structlog, extended health checks (DB, Redis, storage, worker)
-- **Metrics endpoint**: GET /api/v1/metrics (admin-only, text/plain Prometheus format)
-- **Health endpoint**: Extended with database, redis, storage, worker checks
-- **Performance**: Streaming CSV export for contacts and companies (StreamingResponse with own DB session), page_size max 100 enforced (422 for >100)
-- **Scripts**: seed_perf_data.py (--count N), check_indexes.py
-- **Documentation**: README.md updated, docs/admin-guide.md created, docs/api-overview.md created
-- **Config**: .env.example updated with SMTP, storage, secret_key vars
-- **Dependencies**: prometheus-client, structlog added to requirements.txt
-
-## Test Evidence
-- 38/38 tests passed in 24.24s
-- Ruff: All checks passed
-- Docs: All files present (README.md, docs/admin-guide.md, docs/api-overview.md)
-
-## Next Steps
-- T11: Next task in task graph (if any)
-- Verify AC11 (ARQ background job for >1000 records CSV export) — requires ARQ worker running
-- Run full test suite to check for regressions
+## Next Step
+- Phase 3 → Phase 4 transition (requires user approval)
+- Phase 4: Test (test_debug_engineer)
