add Game Axiom, Domain Verification

[jlsegb]

Description

Adds a Game Axiom Domain Connect template for domain ownership verification. The template publishes the Cloudflare custom hostname ownership TXT record at _cf-custom-hostname using the standard Domain Connect host parameter for apex and subdomain verification.

The TXT record value is intentionally a bare variable because Cloudflare Custom Hostnames provides the complete ownership verification token and Game Axiom must publish that exact value for verification to succeed.

Type of change

Please mark options that are relevant.

• New template

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

Additional local validation: dc-template-linter -cloudflare -loglevel error -tolerate info -logos gameaxiom.com.domain-verification.json

Checklist of common problems

Mark all the checkboxes after conducting the check. Comment on any point which is not fulfilled.
See Template Quality Guidelines for details and rationale on each rule.

• syncPubKeyDomain is set — this is mandatory; omitting it requires explicit justification in the PR description or the PR will be rejected
• warnPhishing is not set alongside syncPubKeyDomain — the two must not appear together
• syncRedirectDomain is set whenever the template uses redirect_uri in the synchronous flow
• no TXT record contains SPF content ("v=spf1 ...") — use the SPFM record type instead
• txtConflictMatchingMode is set on every TXT record that must be unique per label or content prefix (e.g. DMARC)
• no variable is used as a bare full record value (e.g. @ TXT "%foo%") unless necessary — prefer @ TXT "service-foo=%foo%"; if bare, justify in the PR description
• no bare variable is used as the full host label — the non-variable parts are fixed to limit misuse (e.g. %dkimkey%._domainkey, not %dkimhost%); if bare, justify in the PR description
• no variable is used in the host field to create a subdomain — use the host parameter or multiInstance instead
• %host% does not appear explicitly in any host attribute
• essential is set to OnApply on records the end user may need to modify or remove without breaking the template (e.g. DMARC)

essential is not set because this is a provider-issued ownership verification token and should remain managed by the Game Axiom verification flow rather than independently edited by the end user.
