Add `*_authentik_forward_auth` + `*_authentik_forward_auth_url` knobs to
both roles. When enabled:
* drawio: traefik attaches a ForwardAuth middleware pointing at the
authentik embedded outpost; unauthenticated requests get redirected
to log in and downstream sees X-Authentik-* identity headers.
* garage WebUI: same ForwardAuth wiring, and `AUTH_USER_PASS` is dropped
from the container env so authentik is the only gate. Tasks now key
the htpasswd hash workflow off `_garage_webui_htpasswd_active`
(`webui_enabled AND NOT authentik_forward_auth`); when authentik
fronts the UI we skip hashing entirely. htpasswd hash is also now
cached on disk and re-verified via `htpasswd -vbB` so unchanged
passwords stop showing as `changed=true` on every run.
Both knobs default to `false`, preserving existing htpasswd/plain behaviour.
- Drop `recreate: always` from collabora/drawio/homarr/opencloud/traefik
handlers and the authentik_outpost_ldap start task. `up -d` with
`state: present` already recreates exactly the services whose
compose definition changed; the blanket recreate was forcing
restarts even when nothing relevant moved.
- Rewrite the `*_domains` Traefik Host loop to the `Host(\`a\`) ||
Host(\`b\`)` form across authentik/collabora/garage/nextcloud so the
rule still matches when traefik can't normalize the comma-form into
the same canonical shape.
- Traefik: add `traefik_acme_tcp_only` (sets LEGO_EXPERIMENTAL_DNS_TCP_ONLY)
and `traefik_acme_disable_ans_checks` (disables lego's authoritative-NS
propagation check) for environments where the DNS path between the
traefik container and the zone's nameservers is constrained.
- Traefik DMZ collector: two-step merge so a `traefik_dmz_exposed_services`
entry that sets its own `backend_host` wins over the host fallback;
lets a route target an internal FQDN covered by the backend cert's
SANs instead of the raw IP.
- Nextcloud: add `nextcloud_notify_push_domain` override for the
`occ notify_push:setup` call so the setup check can hit an internal
FQDN instead of hairpinning through the DMZ. Push router now matches
every entry in `nextcloud_domains`.
- Nextcloud: also %2F-escape slashes in the postgres user/password
inside the notify_push DATABASE_URL.
- Refactor: collapse `*_domain` + `*_extra_domains` into a single
`*_domains` list across authentik, collabora, garage and nextcloud
roles. First entry is the canonical FQDN (used for OVERWRITEHOST,
BASE_URL, notify_push setup and garage root_domain).
- Authentik blueprint: guard the OAuth sources block so an empty
`authentik_login_sources` no longer renders an invalid YAML key.
- Nextcloud: introduce `nextcloud_collabora_public_domain` and set
Collabora's `public_wopi_url` separately from the server-to-server
`wopi_url` so browsers can reach Collabora via the public name while
Nextcloud still talks to it on the internal one.
- Nextcloud: URL-encode the postgres user/password in DATABASE_URL.
