[Bug] USB Passthrough Enumerated (0bda:f179 & SIM Modems) but fails to load firmware across multiple devices

[OPX-Aminul]

### Environment & Device Info
- **Host Devices:** Xiaomi and various other Android devices
- **Guest OS:** Alpine Linux (Podroid/QEMU)
- **USB Adapters:** Realtek 802.11n (`0bda:f179` / RTL8188FU), LTE/SIM Cellular Modems

### Problem Description
The USB passthrough and hardware enumeration are completely successful (`lsusb` shows `0bda:f179 Realtek 802.11n`). However, the `wlan0` (or cellular) interface is not generated because the guest kernel cannot find the required firmware binary files inside the base RootFS. 

This issue is not isolated to a single phone model or a single adapter type—it occurs across multiple Android devices and affects both Wi-Fi and SIM/Cellular USB dongles using similar driver architecture.

### Root Cause
The minimal Alpine Linux RootFS lacks essential hardware firmware packages (`linux-firmware-rtlwifi`, cellular modem firmwares, etc.). While some Android ROMs happen to carry these binaries natively, many devices (like Xiaomi) do not, leading to `error -2` (File Not Found) in the VM.

### Suggested Fix
Please include comprehensive wireless and modem firmware packages (e.g., `linux-firmware-rtlwifi`, `linux-firmware-other`) or embed `/lib/firmware/` binaries directly into the Alpine RootFS / Dockerfile image build step:

```dockerfile
RUN apk add --no-cache linux-firmware-rtlwifi linux-firmware
