Add DNS provider for Com Laude

[ldez]

Closes #2880

Ping @lackern-se-digicert, can you run the command with your domain, credentials, etc. (and put the output of this command to a comment)?

make build
rm -rf .lego

COMLAUDE_USERNAME="xxx" \
COMLAUDE_PASSWORD="yyy" \
COMLAUDE_API_KEY="zzz" \
COMLAUDE_GROUP_ID="abc" \
./dist/lego --dns comlaude -d '*.example.com' -d example.com -s https://acme-staging-v02.api.letsencrypt.org/directory run

Note that the wildcard domain is important.

How to test this PR?

1. You need Go
2. Check out the PR:

   git clone https://github.com/ldez/lego.git
   cd lego
   git checkout feat/dns/comlaude

3. Compile lego:
   • if you have make: make build
   • if you don't have make: go build -o dist/lego ./cmd/lego
4. Run the following command with your information (email, domain, credentials):

   COMLAUDE_USERNAME="xxx" \
   COMLAUDE_PASSWORD="yyy" \
   COMLAUDE_API_KEY="zzz" \
   COMLAUDE_GROUP_ID="abc" \
   ./dist/lego --dns comlaude -d '*.example.com' -d example.com -s https://acme-staging-v02.api.letsencrypt.org/directory run

5. Before each run of the command, you should clean your local environment:

   rm -rf .lego

Thank you for your patience to review the request, unfortunately, I do not have direct access to the privilege information required to run the commands.

OK, but why have you asked for the addition of this provider? 🤔

Perhaps you could ask someone to test the PR?

[lackern-se-digicert]

Thank you for waiting. This is the information shared by end user, hope it helps.

Test result (Windows 11 / Git Bash)
Go: go1.26.2 windows/amd64
lego: v4.32.0+dev-detach windows/amd64
Command used (redacted env vars):

COMLAUDE_USERNAME="***" 
COMLAUDE_PASSWORD="***" 
COMLAUDE_API_KEY="***" 
COMLAUDE_GROUP_ID="***" \
./dist/lego --dns comlaude -d '*.example.com' -d example.com -s https://acme-staging-v02.api.letsencrypt.org/directory run

Result: ACME order starts, but DNS provider fails during Com Laude login JSON parsing.
Error:

comlaude: API login: unable to unmarshal response: [status code: 200] body: {...}
json: cannot unmarshal object into Go struct field LoginResponse.data of type []internal.TokenInfo

Sanitized response shape from Com Laude:

{
  "errors": [],
  "messages": [
    {
      "code": "correct_login_details",
      "message": "Log-in details correct"
    }
  ],
  "data": {
    "token_type": "Bearer",
    "expires_in": 7200,
    "access_token": "<redacted>",
    "refresh_token": "<redacted>",
    "dnsdashboard_link": 1
  },
  "status_code": 200
}

It looks like data is an object, but the code expects []TokenInfo. Suggest changing LoginResponse.data to a single object (or supporting both object/array).
(Also note: cleanup warnings “unknown record ID or zone ID” appear after the failure, likely because Present never completed.)

This means that the API documentation is wrong.

https://api.comlaude.com/docs#/Auth/POST.api_login

{
  "errors": [
    "string"
  ],
  "messages": [
    {
      "code": "correct_login_details",
      "message": "Log-in details correct"
    }
  ],
  "data": [
    {
      "token_type": "Bearer",
      "expires_in": 7600,
      "access_token": "",
      "refresh_token": "",
      "dnsdashboard_link": 1
    }
  ],
  "status_code": 200
}
