6b4b7647e fixed this for synapse-usage-exporter only. A checkout owned by
a different user makes the git task fail from then on, either with a
permission error or with git's dubious-ownership protection, until
someone removes the directory on the host by hand. It gets into that
state when the matrix user's uid changes (a server migration or a restore
onto a differently numbered user), when an earlier clone ran as another
user, or when someone runs git as root inside the checkout.

Every other role cloning a repository onto the server was open to the
same failure, so ensure the checkout's ownership recursively before
updating it at the remaining 54 sites.

The three matrix-synapse ext clones also gain force=yes. They were the
only on-server clones without it, which left a checkout that an
interrupted run had half-written wedged, instead of repaired on the next
run.

matrix-matrixto used to clone as root into a directory that nothing ever
chowned, unlike every other role. It now becomes the matrix user too.

The Element Web and SchildiChat Web theme checkouts live on the Ansible
controller, where correcting ownership is not ours to do, so they merely
mark the checkout as a safe directory for git.

* 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.

Replaces `community.docker.docker_image` with the modern
`docker_image_pull` module. Drops the `ansible_version` compatibility
ladder and the now-redundant `_container_image_force_pull` variable
(the new pull module handles registry refresh natively via `pull: always`).

Track config/image/systemd changes via register: directives and compute
a _restart_necessary variable for each service role, allowing the
systemd_service_manager to skip unnecessary restarts during install-* runs.

Covers 22 service roles: alertmanager-receiver, appservice-draupnir-for-all,
bridge-mautrix-wsproxy (+ syncproxy), cactus-comments, cactus-comments-client,
corporal, element-admin, ldap-registration-proxy, livekit-jwt-service, matrixto,
pantalaimon, prometheus-nginxlog-exporter, rageshake, registration, static-files,
sygnal, synapse-admin, synapse-auto-compressor, synapse-reverse-proxy-companion,
synapse-usage-exporter, and user-verification-service.
