Finalmask configuration is not included in generated connection links

[GogoLike]

Describe the bug

When adding a connection configuration that uses finalmask, the subscription link does not include the configuration parameters for finalmask. The link correctly includes parameters like vless, xhttp, kcp, etc., but the fm= parameter is missing.

To Reproduce

1. Create any Xray configuration with the finalmask section enabled.
2. Create a user with access to this configuration.
3. Open the user's subscription link.
4. Check the generated connection link for this specific inbound.
5. The fm= parameter will be missing.

Expected behavior

The generated subscription link should include the fm= parameter corresponding to the finalmask configuration.

Example: vless://b318a3f4-2503-4656-a249-74a759dfaba6@ip:10000?encryption=none&security=none&fm=%7B%22udp%22%3A%5B%7B%22type%22%3A%22header-dtls%22%7D%5D%7D&type=xhttp&path=%2F&mode=auto#Vless-xHTTP-Finalmask

Additional context

Example Xray inbound configuration:

{
  "tag": "Vless+xHTTP+Finalmask",
  "port": 10000,
  "protocol": "vless",
  "settings": {
    "clients": [],
    "decryption": "none"
  },
  "streamSettings": {
    "network": "xhttp",
    "xhttpSettings": {
      "host": "",
      "mode": "auto",
      "path": "/",
      "headers": {},
      "noSSEHeader": false,
      "xPaddingBytes": "100-1000",
      "scMaxBufferedPosts": 30,
      "scMaxEachPostBytes": "1000000",
      "scStreamUpServerSecs": "20-80"
    },
    "finalmask": {
      "udp": [
        {
          "type": "header-dtls"
        }
      ]
    }
  }
}

Actually generated user link (missing fm= parameter):

vless://b318a3f4-2503-4656-a249-74a759dfaba6@ip:10000?encryption=none&type=xhttp&headerType=none&path=%2F&mode=auto#Vless-xHTTP-Finalmask
