- Override devture_systemd_service_manager_conditional_restart_enabled in
  group_vars based on ansible_run_tags: disabled when setup-* tags are used,
  enabled otherwise. This replaces the --extra-vars hack in the justfile and
  ensures consistent behavior for both `just` and raw `ansible-playbook` users.
- Revert justfile setup-all to its original form (no --extra-vars needed).
- Update docs/just.md to reflect tag-agnostic behavior.
- Add CHANGELOG.md entry documenting the conditional restart feature.

- Traefik's service list entry now uses the `traefik_restart_necessary`
  variable (computed by the Traefik role) instead of hardcoded `true`,
  so it is only restarted when its config, systemd unit, or image changed.

- `just setup-all` now passes
  `devture_systemd_service_manager_conditional_restart_enabled=false`
  to force unconditional restarts, matching its "full setup" semantics.

- Document the conditional restart behavior in docs/just.md.

Some benchmarks follow for `just install-service traefik -l matrix.example.com`
when Traefik settings did not change and a restart is not really necessary:

- Before:
  - total time: 56 seconds 🐌
  - Traefik restarted: yes ❌
  - Services that depend on Traefik restarted: yes; all of them restarted ❌

- After:
  - total time: 27 seconds ⚡
  - Traefik restarted: no ✅
  - Services that depend on Traefik restarted: no; none restarted ✅

- `install-service` no longer forces `one-by-one` restart mode

- the coturn priority condition is flipped: only `one-by-one` mode
  needs the delayed priority (1500); all other modes (including
  the new `all-at-once` default) use the normal priority (900)

People who need to time things should do it themselves, explicitly.
Forcing `time` on people is a little rude.

This way, something like `just install-service postgres` will
definitely do a `restart` and not a `stop` + `start` (which may leave
dependant services stopped).

This has potentially been addressed by
7acb5f4b85
as well.

It's now possible to do: `just install-service prometheus -l host.example.com`

It should be noted that this cannot be used for the initial install
of services which require a database or have other dependencies.
Those would typically need to invoke the playbook with
`--tags=install-postgres,install-SERVICE`, etc.

The purpose of this shortcut is to easily rebuild and restart
a single serice subsequently. For those cases, often times there's no need to
reinitialize the database and other components and simply running a
single component's tasks is enough.

We keep the Makefile for now, but don't mention it to new
users anymore.
