Add System Check workflow with serial and network connection options

Browse Source 
Adds workflow_check.py: a read-only diagnostic that queries current network
settings and firmware versions (IOM + Fabric Card) from both IOMs. Accessible
via a new main menu option (3 — System Check); Exit moves to option 4.
Supports both serial console (curl over the serial session) and direct network
(HTTPS to management IP) connection methods.

- The firmware file must be re-uploaded between the IOM and Fabric Card steps — it does not persist after the first update (firmware quirk, documented in `_update_fabric_fw()`)
- Scans the current working directory for firmware files (`.bin`, `.img`, `.fw`, `.hex`, `.zip`, `.tar`, `.tgz`, `.gz`) and presents them as a numbered list before falling back to manual path entry
### 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
- **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

## Planned Features
- Network-based IOM network configuration (`workflow_network.py`) — same config workflow as serial but connecting via the IOM's existing IP address using `Admin` credentials, for cases where the IOM is already reachable on the network
- Auto-detect password from serial login prompt — the IOM BMC serial number (e.g. `MXE3000043CHA007`) appears to be embedded in the login prompt hostname; if confirmed on a live system, this could allow `_login_serial_console()` to skip the manual password prompt
