Swift Paperless needs REST API v3-9; server was on 2.13 (v1-5 only),
causing 406 on /api/token/ for all phone uploads. v3 requires
PAPERLESS_DBENGINE explicit instead of inferred from PAPERLESS_DBHOST.
allauth defaulted to ACCOUNT_EMAIL_VERIFICATION=mandatory, and building the confirmation link 500'd with NoReverseMatch on account_confirm_email (paperless-ngx doesn't wire up that view, no SMTP configured either). Authentik already verifies identity via OIDC, so this step is redundant.
Fixes controlplane.tftpl's install.wipe:true (should be false, live CPs already run false) and syncs coredns Corefile back to what's actually deployed (drops an unrolled-out, stale Kong-era rewrite).
