`tencentcloud_teo_origin_acl` sends invalid `"L4EnableMode": "specific"` when `l4_proxy_ids` is omitted/empty

[scottwallacesh]

When configuring a tencentcloud_teo_origin_acl resource without defining Layer 4 proxy protection (i.e., l4_proxy_ids is omitted, set to null, or set to []), the provider incorrectly injects "L4EnableMode": "specific" into the EnableOriginACL API request payload.

Because L4ProxyIds is empty, the EdgeOne API strictly rejects the payload, as "L4EnableMode": "specific" requires at least one valid L4 proxy ID to be passed.

The provider should either omit L4EnableMode entirely from the JSON request or pass a valid mode (like "all") when no L4 proxies are defined.

Expected Behavior

A successful API call configuring only the Layer 7 hosts. The provider should recognize that l4_proxy_ids is empty and either omit "L4EnableMode" from the request entirely, or set it to "all" so that the EdgeOne API validation passes.

Actual Behavior

The API rejects the request with a 400 InvalidParameterValue error because the provider defaulted to "L4EnableMode": "specific" without providing the required L4 proxy IDs.

i.e.

{
    "ZoneId": "zone-xxxxxxxxx",
    "L7EnableMode": "specific",
    "L7Hosts": [
        "example.com.cn"
    ],
    "L4EnableMode": "specific",
    "OriginACLFamily": "gaz"
}

Steps to Reproduce

1. Create a tencentcloud_teo_origin_acl resource.
2. Define l7_hosts.
3. Omit l4_proxy_ids or explicitly set it to [].
4. Run terraform apply.
