feat: redesign collection UI + add StopHostAfterCollect + TCP ping pre-probe

- Single "Подключиться" button flow: probe first, then show collect options
- Power management checkboxes: power on before / stop after collect
- Modal confirmation when enabling shutdown on already-powered-on host
- StopHostAfterCollect flag: host shuts down only when explicitly requested
- TCP ping (10 attempts, min 3 successes) before Redfish probe
- Debug payloads checkbox (Oem/Ami/Inventory/Crc, off by default)
- Remove platform_config BIOS settings collection (unreliable on AMI)
