Update syncPubKeyDomain to achene.app

[PeteJStewart]

Description

Corrects syncPubKeyDomain from domainconnect.achene.app to achene.app.
Update logo URL.

Background: Cloudflare builds the public-key TXT lookup as {key}.{syncPubKeyDomain}. The key URL parameter carries the sub-label prefix (domainconnect), so the full lookup domain must be domainconnect.achene.app. The previous value (domainconnect.achene.app) caused Cloudflare to query domainconnect.achene.app.domainconnect.achene.app, which does not exist. The JWT returned had perms: [] and the flow failed silently.

No DNS records were changed — only the syncPubKeyDomain metadata field and the logo URL.

Type of change

• New template
• Bug fix (non-breaking change which fixes an issue in the template)
• New feature (non-breaking change which adds functionality to the template)
• Breaking change (fix or feature that would cause existing template behavior to be not backward compatible)

How Has This Been Tested?

• Template functionality checked using Online Editor
• Template file name follows the pattern <providerId>.<serviceId>.json — achene.app.customdomain.json
• resource URL provided with logoUrl is actually served by a webserver — https://achene.app/favicon-light.svg

Checklist of common problems

• syncPubKeyDomain is set — achene.app
• warnPhishing is not set alongside syncPubKeyDomain
• syncRedirectDomain is set — achene.app (used in the synchronous redirect flow)
• no TXT record contains SPF content — no TXT records in this template
• txtConflictMatchingMode — not applicable, no TXT records
• no variable is used as a bare full record value — no variables used in this template
• no bare variable is used as the full host label — no variables used
• no variable is used in the host field to create a subdomain — host parameter is used via hostRequired: true
• %host% does not appear explicitly in any host attribute — host is "@" (expands to the provided host parameter)
• essential — not applicable, no records the end user would need to modify independently

Online Editor test results

hostRequired: true so apex test is not required — only subdomain test needed.
