Bundle of cross-role changes for the gymb services deployment:
- Traefik routers: OR-combine opnform/homarr/bookstack Host rules with new
*_extra_domains (internal *.int.* FQDNs for a DMZ reverseproxy), and emit
tls.certresolver only when traefik_cert_mode == acme (drawio, homarr,
opnform, send).
- Split-horizon: bookstack_extra_hosts / opnform_extra_hosts add container
/etc/hosts overrides so containers reach the IdP public FQDN over the LAN.
- bookstack: assert the OIDC issuer resolves concretely (reject "//v2.0"),
allowing non-Entra IdPs that override bookstack_oidc_issuer.
- homarr: derive the bcrypt salt from the password digest so the admin hash
is idempotent — no spurious template changes / container restarts.
- opnform: PATCH an existing OIDC connection instead of skipping (applies
corrected inventory on re-run); add OIDC_FORCE_LOGIN (enabled only after
bootstrap) and an optional direct-SSO ingress entrypoint.
Docs: READMEs and meta/argument_specs.yml updated for all new variables.
