add OneBookPlus, 2 templates

[corporatebishal]

Description

New provider: OneBookPlus (onebookplus.com / onebookplus.com.au), an Australian small-business platform with a website builder. Two templates connect a customer's domain to their OneBookPlus website:

• onebookplus.com.website (hostRequired: true) — CNAME for the connected subdomain host + a prefixed ownership-verification TXT.
• onebookplus.com.website-apex — apex A record + the same TXT.

They are deliberately split so a subdomain connect can never rewrite a customer's existing apex A records (Domain Connect replaces same-type records at the same host unconditionally). Record targets are hard-coded — the only variable is the per-tenant verification token, written with a fixed prefix.

Type of change

Please mark options that are relevant.

• 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 used

Both templates pass dc-template-linter -loglevel error -tolerate info with zero findings. The signing public key is published at dck1.onebookplus.com (two TXT fragments, a=RS256,t=x509) and verified end-to-end against the production signer.

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) — All on the verification TXT
• 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 — verification TXT uses the fixed prefix obp-site-verify=
• 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 variables in any host
• 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) — set on the verification TXT
