make leakix api key mandatory

[liquidsec]

Summary

• leakix.net now returns HTTP 401 "Incorrect API Key" for all endpoints (including `/api/subdomains/...` and the `/host/1.1.1.1` ping URL) when no key is provided. Verified manually against the live service.
• Remove the keyless setup override and conditional header logic. The module now uses the standard `subdomain_enum_apikey.setup()` flow, which soft-fails with "No API key set" if no key is configured.
• Add `auth_required: True` to meta so the module listing correctly shows `Yes` in the API Key Required column.
• Drop the `TestLeakIX_NoAPIKey` test, since keyless mode is no longer supported by the upstream API.
