matrix-bot-draupnir and matrix-appservice-draupnir-for-all share the same
upstream container image. When both are enabled and force-pull is on
(e.g. when pinning to a rolling tag like `latest` or `main`), the second
role to run during a single playbook invocation sees the image as already
up-to-date locally because the first role just pulled it. The
community.docker.docker_image module reports `changed: false` in that
case, so the second role's restart_necessary stays false and the
conditional restart logic skips it. Result: the first service picks up
the new image on restart, while the second keeps running the old one.
For other versions which don't get force-pulled (other than `latest`),
systemd service files also get updated by the playbook and these updates
done by each role properly flip the "requires restarting" variable
regardless of pulling. So it's just force-pulling that causes the problem.
Treating force-pull itself as a restart trigger sidesteps the lossy
"did this specific pull task fetch new bytes" heuristic. The downside
is that both Draupnir services now restart on every run when force-pull
is enabled, even when the upstream image has not moved. That is a small
amount of waste compared to silently running an outdated container.
Localized to these two roles via a comment that documents the
constraint, rather than applied playbook-wide, since this is the only
known image-sharing pair and other roles do not need the extra
restarts.

For each of the 34 roles (3 clients, 9 bots, 22 bridges), this commit:
- Adds `_restart_necessary: false` default variable
- Adds `register:` directives to config/image/systemd tasks
- Computes `_restart_necessary` via set_fact (OR of all .changed results)
- Wires `(_restart_necessary | bool)` in group_vars/matrix_servers
This allows the systemd service manager to skip unnecessary restarts
when running install-* tags and nothing actually changed.
Service roles and complex multi-service roles will follow separately.

These variables track whether a database migration necessitates a service
restart. The new name avoids confusion with the conditional restart
feature introduced in af193043/9accc848/4a8df138, where
devture_systemd_service_manager handles restarting services whose
configuration or image changed. The old _requires_restart name was
ambiguous — it could be mistaken for the systemd_service_manager
mechanism — so _migration_requires_restart makes the purpose explicit.
