Add spinlab.studio Platform template

[SwartZCoding]

Description

New Domain Connect template for Spinlab (spinlab.studio) — a white-label casino hosting platform. This template configures DNS records to connect a customer's domain to the Spinlab infrastructure.

Records configured:

• APEXCNAME @ to apex.spinlab.studio (apex domain with CNAME flattening)
• CNAME www to apex.spinlab.studio
• CNAME api to apex.spinlab.studio

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
• resource URL provided with logoUrl is actually served by a webserver

Checklist of common problems

• digital signatures are used and syncPubKeyDomain specified
• syncRedirectDomain is specified when intended to use redirect_uri parameter in the synchronous flow — N/A (not using redirect_uri)
• no TXT record with SPF content instead of using SPFM record type on APEX — N/A (no TXT records)
• txtConflictMatchingMode is set on TXT records which shall be unique on a label (like DMARC) — N/A (no TXT records)
• variables are set to the smallest scope needed — N/A (no variables, all records point to fixed CNAME target)
• no variables as a host name to apply template on subdomain instead of standard host parameter
• no explicit usage of %host% variable in host attribute
• essential setting is used on records — N/A (all records are essential by default)

APEXCNAME is an extension, so support for it may vary.
Technically template is ok though.
Consider if maybe an alternative template without APEXCNAME (regular A/AAAA) shall be created so that you can choose based on template discovery response.
