Limit serial workflows to IOM1 only — IOM2 unreachable over serial

Browse Source 
The serial cable connects to IOM1's console port. IOM2 cannot be queried
or configured via the serial connection. Updated all serial-path code to
reflect this:

workflow_serial.py:
- fetch_current_config: query IOM1 only, single-row table
- collect_network_config: prompt for IOM1 settings only, drop IOM2 section
- apply_configuration: apply to IOM1 only, single-row result table
- print_summary: IOM1-only table, updated warning text

workflow_check.py (_check_via_serial):
- Query IOM1 only for network settings, IOM firmware, and Fabric Card firmware

CLAUDE.md updated to document the IOM1-only serial limitation.

## Workflows

5-step workflow using the USB serial cable:
5-step workflow using the USB serial cable. **Serial access is limited to IOM1 only** — the cable connects to IOM1's console port; IOM2 cannot be queried or configured this way.
1. Detect USB serial device (`/dev/ttyUSB*`, `/dev/ttyACM*`, `/dev/ttyU*`)
2. Open 115200-baud 8N1 connection and wake the IOM console
3. Query current network settings via Redfish (`GET` over `127.0.0.1`)
4. Collect new settings from user (Static IP or DHCP)
5. Apply via Redfish `PATCH` over `127.0.0.1`
3. Query IOM1 current network settings via Redfish (`GET` over `127.0.0.1`)
4. Collect new settings from user (Static IP or DHCP) for IOM1
5. Apply via Redfish `PATCH` over `127.0.0.1` to IOM1

### 3 — System Check (`workflow_check.py`)
Read-only diagnostic workflow — queries current network settings and firmware versions, makes no changes:
- **Serial:** logs in via serial console, queries both IOMs using `_serial_redfish_request()` (curl over the serial session); covers network settings, IOM firmware, and Fabric Card firmware
- **Serial:** logs in via serial console, queries IOM1 only using `_serial_redfish_request()` (curl over the serial session); covers network settings, IOM firmware, and Fabric Card firmware. IOM2 is not reachable over serial.
- **Network:** prompts for management IP(s), queries via direct HTTPS using `Admin` credentials; reuses `_redfish_request()`, `_get_iom_fw_version()`, `_get_fabric_fw_version()` from `redfish.py`
- Displays results in two tables: network configuration and firmware versions
- User selects Serial, Network, or Cancel at the sub-menu prompt
