Allow Custom System Vendor and Product Name Override in Settings

[d19dotca]

Problem

Some VPS and dedicated server providers (OVH in my case) ship servers with placeholder DMI/SMBIOS information that shows as "To Be Filled By O.E.M." in the Server page of Cloudron. This information is read from /sys/devices/virtual/dmi/id/ and cannot be changed at the OS level since it's stored in read-only firmware. This results in some annoyances in the Server page when reviewing the details.

Current display in Cloudron Server page:

• System Vendor: To Be Filled By O.E.M.
• Product Name: To Be Filled By O.E.M.

Proposed Solution

Add optional configuration fields to allow administrators to override the system vendor and product name displayed in Cloudron's Server page. This can help not only in allowing us to be more technically accurate, but also could be used by admins for quickly identifying prod vs stage servers, or the type of Cloudron server that's running if managing multiple for example.

Proposals:

Option 1: Configuration File

Add optional fields to a Cloudron config file, for example /home/yellowtent/platformdata/configs/system.json:

{
  "systemVendorOverride": "OVH",
  "productNameOverride": "SYS-GAME-2"
}

Option 2: Settings UI

Add fields in System → Settings or Server:

• Custom System Vendor (optional)
• Custom Product Name (optional)

If these fields are populated, use them instead of the DMI values.

Option 3: Environment Variables

Allow setting via environment variables:

CLOUDRON_SYSTEM_VENDOR="OVH"
CLOUDRON_PRODUCT_NAME="SYS-GAME-2"

My preference would be option #2 above that's only editable by administrators.

Code Reference

The relevant code is in system.js in the getInfo() function:

async function getInfo() {
    // ... existing code ...
    
    const sysVendor = safe.fs.readFileSync('/sys/devices/virtual/dmi/id/sys_vendor', 'utf8') || '';
    const productName = safe.fs.readFileSync('/sys/devices/virtual/dmi/id/product_name', 'utf8') || '';
    
    // ... existing code ...
    
    return {
        sysVendor: sysVendor.trim(),
        productName: productName.trim() || productFamily.trim(),
        // ... other fields ...
    };
}

Benefits

1. Cosmetic Improvement: Server page displays meaningful information
2. Multi-server Management: Easier to identify servers when managing multiple Cloudron instances
3. No Breaking Changes: Optional feature, defaults to current behavior

This is related in part to https://forum.cloudron.io/post/81065. Between OVH's indifference to setting these BIOS firmware attributes, and my mild OCD... lol, I'm hoping we can add this as a small nice-to-have improvement for users.
