Add gallerydeals.com custom-domain template

[makegravity]

Description

Adds a Domain Connect template for GalleryDeals, an online auction platform for auction houses. It lets a customer connect their domain to the platform in one click: it points the site at our host and authenticates the domain for sending auction email.

• providerId: gallerydeals.com
• serviceId: custom-domain
• Records: a site CNAME at the fixed bid subdomain (customer domain to our Azure web app), an asuid.bid domain-ownership-verification TXT (Azure App Service), and three SendGrid automatic-security email CNAMEs: the mail label %sgMailHost% plus two static DKIM selectors (s1._domainkey / s2._domainkey) that share the SendGrid account link %sgLink%.
• Fixed bid subdomain, no hostRequired: the site records live at the fixed bid label, so the CNAME is never at the zone apex (where a CNAME cannot sit); the template applies at the zone level, so no host parameter is required.
• Scoped variables: only two remain, %sgMailHost% (SendGrid mail CNAME label) and %sgLink% (SendGrid account link prefix), both documented in variableDescription. The site target, asuid value, and DKIM selectors are all static literals.
• Signed: syncPubKeyDomain = gallerydeals.com (RS256; public key published at _dcpubkey.gallerydeals.com).

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?

Please mark the following checks done

• Template functionality checked using Online Editor
• Template file name follows the pattern <providerId>.<serviceId>.json
• resource URL provided with logoUrl is actually served by a webserver - N/A, no logoUrl is set in this template

Checklist of common problems

• syncPubKeyDomain is set
• warnPhishing is not set alongside syncPubKeyDomain
• syncRedirectDomain is set whenever the template uses redirect_uri in the synchronous flow
• no TXT record contains SPF content - the only TXT is the asuid.bid ownership-verification record
• txtConflictMatchingMode - N/A, the single asuid TXT is not a uniqueness-constrained record (not DMARC-style)
• no variable used as a bare full record value - the asuid TXT value and the site CNAME target are static literals; %sgLink% only appears embedded inside a larger ...sendgrid.net value, never as the whole value
• no bare variable used as the full host label - site CNAME at bid, TXT at asuid.bid, DKIM at static s1._domainkey / s2._domainkey; the only variable host is %sgMailHost%, the SendGrid mail label, matching the SendGrid email-whitelabel / domain-auth templates
• no variable used in the host field to create a user-chosen subdomain - %sgMailHost% is the SendGrid-issued mail label, not a user-supplied name
• %host% does not appear explicitly in any host attribute
• essential OnApply - N/A, no records the end user should modify or remove (no DMARC)
