chore(presets): update ClaudeCN referral link to claudecn.ai/register

Move the ClaudeCN invite link to https://claudecn.ai/register?aff=HEL9
across all 7 app presets (apiKeyUrl) and the four README sponsor rows
(banner + CTA, which previously pointed at the bare .top domain with no
referral tag). The websiteUrl and claudecn.top API endpoints are kept
unchanged, so only the registration/referral link moves to the new
domain and code.
