Итерация 2: сканирование сети

- Phinx миграции: network_ranges, scan_jobs, discovered_hosts, audit_log
- Models: NetworkRange, ScanJob, DiscoveredHost
- Repositories с CRUD для всех сущностей
- NetworkScanner: ping sweep + TCP connect + ARP table + reverse DNS
- PingScanner, TcpPortScanner (curl_multi для параллелизма), ArpTableReader
- HostFingerprintService: vendor detection + confidence scoring
- ScanJobRunner + CLI worker (bin/run-scan-worker.php)
- Discovery UI: управление диапазонами, запуск скана, таблица находок
- NetworkRangeController с валидацией CIDR
- Обновлён public/index.php с DI конфигурацией для новых сервисов
