The /_tuwunel namespace carries Tuwunel's ad-hoc routes (server_version,
local_user_count) and its native OpenID Connect provider endpoints
(/_tuwunel/oidc/...), which a reverse proxy must route for OIDC login
to work. Add public (enabled by default, like the client API) and
internal Traefik label groups.

Tuwunel serves the Synapse administration API under /_synapse/admin,
but the role only routed /_matrix, so admin dashboards and moderation
bots could not reach it. Add public and internal Traefik label groups
mirroring the matrix-synapse role, and enable them automatically when
Ketesa, Element Admin, or Draupnir is installed.

As of tuwunel v1.8.0, the ip_range_denylist applies to push gateway
delivery as well, so surface it as an Ansible variable using the
default/auto/custom merge pattern. The default mirrors tuwunel's own
upstream denylist (RFC1918, loopback, multicast, and other unroutable
ranges), matching the identical list already used for Synapse's
matrix_synapse_url_preview_ip_range_blacklist.

* feat: support container_network=host across all roles + systemd templates

Mirror the pattern Slavi introduced for matrix-coturn (aafa8f0) across the
fork: every 'Ensure X container network is created' task gets a
'when: <var> not in ["", "host"]' guard so MDAD does not try to
docker_network create a network literally named 'host' (returns 403,
since host is a pre-defined Docker network).

Mirror the same guard in every systemd unit template that does
'ExecStartPre=docker network connect <addnet> <container>' loops over
matrix_<role>_container_additional_networks: skip the connects when the
container is on host networking (where additional --network attaches
are invalid).

Unblocks DiD setups where MDAD-managed containers share their host's
network namespace (matrix-mdad outer compose service joined to central
postgres/openldap networks) to reach external services on the outer
Docker daemon.

* Simplify container network guards (!= 'host') and fix duplicate when

Guarding on the empty string ('') as well was misleading: systemd unit
templates still render an unconditional --network= flag, so an empty
network value produces a broken docker create command. Only 'host' is
actually supported, so only guard on that. This also matches the
existing convention in the Traefik role
(when: traefik_container_network != 'host').

Also fix a duplicate when key in the meshtastic-relay role, where the
network-creation task already had a when condition - the two are now
combined into a list.

This release adds opt-in server-level enforcement of MSC4284 policy
servers via two new `[global]` keys: `enable_policy_servers` and
`policy_server_request_timeout`. Surface both as Ansible variables
matching tuwunel's upstream defaults (off, 5s timeout) and refresh the
docs section that previously claimed MSC4284 needed no playbook
configuration.

Closes https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/5213.

Files in this role were ported from matrix-continuwuity (which carries
2025 attribution), so the year range should reflect that the underlying
content predates 2026.

Repo convention is to pin homeserver-role versions to a specific tag
so renovate can track updates and so the deployment is reproducible.

Tuwunel is a Matrix homeserver maintained by the matrix-construct
organisation. See https://matrix-construct.github.io/tuwunel/.

The rendered TOML emits only keys exposed as Ansible variables; the
rest fall back to tuwunel's upstream defaults. Anything not surfaced
can be set via the TUWUNEL_* env extension or by overriding the
template path.

Popular features Tuwunel adds variables for:

- OAuth2/OIDC identity providers (a list of `[[global.identity_provider]]`
  blocks; brand-aware defaults for Google, GitHub, Keycloak, MAS, etc)
- LDAP and JWT authentication
- Media storage providers (native local and S3 with multipart upload)
- RocksDB tuning (compression, direct_io, parallelism, online backups)
- Native TLS dual-protocol mode
- Blurhashing, Sentry crash reporting

Auto-wired from existing playbook globals: well-known client URL,
TURN/coturn, MatrixRTC LiveKit URL, federation.

The `tuwunel-migrate-from-conduwuit` tag performs a binary-swap
migration. Migration from any other Conduit derivative is unsupported
and would corrupt the database.
