The metrics endpoint was the only thing this bridge ever routed through
Traefik. With it gone, the container was still labeled `traefik.enable=true`
without defining any router, which makes Traefik fall back to its default
rule and produce a router pointing at nothing. It was also joining the
reverse-proxy network for no reason.

Bridges based on bridgev2 no longer expose a metrics endpoint, so the
playbook was publishing a Traefik route which could only ever yield an
HTTP 502.

only ever yield an HTTP 502.

The playbook exposes service metrics under a single endpoint
(`https://matrix.example.com/metrics/*`), controlled by
`matrix_metrics_exposure_enabled` and friends. synapse-usage-exporter was
not wired into this at all, so its metrics could only be scraped by the
integrated Prometheus and were unreachable for an external one.

The role had no metrics router whatsoever. Its only Traefik router (for
the `/report-usage-stats/push` ingestion endpoint) was gated on
`matrix_synapse_usage_exporter_container_labels_traefik_enabled`, which
defaulted to `matrix_synapse_usage_exporter_proxying_enabled`. Adding a
metrics router under that same switch would have meant that exposing
metrics also publishes the ingestion endpoint, so the master switch now
defaults to `true` and each router carries its own conditional.

Despite its generic name, `matrix_synapse_usage_exporter_proxying_enabled`
only ever concerned the endpoint that Synapse pushes usage statistics
**to**, never the metrics endpoint that Prometheus reads **from**. The
documentation now says so explicitly.

Until now, ntfy metrics could only be collected by an external Prometheus
server. Enabling the integrated Prometheus (`prometheus_enabled: true`)
now also has it scrape ntfy, like it does for the other services.

The playbook exposes service metrics under a single endpoint
(`https://matrix.example.com/metrics/*`), controlled by
`matrix_metrics_exposure_enabled` and friends. ntfy was not wired into
this at all, so enabling metrics exposure did not expose ntfy's metrics
and enabling Basic Authentication did not protect them.

We have ntfy serve its metrics on a dedicated port, instead of on its
regular HTTP port. Serving them on the regular HTTP port also makes them
reachable at `https://ntfy.example.com/metrics`, where nothing protects
them, as ntfy does not apply its own access-control rules to the metrics
endpoint.

Since the introduction of the synapse-usage-exporter role (55f869254, #3442), group_vars/matrix_servers was overriding matrix_synapse_report_stats_endpoint with an empty string whenever synapse-usage-exporter was disabled, clobbering the role's matrix.org default.

For deployments that enable matrix_synapse_report_stats, Synapse would then try reporting statistics to an empty URL, failing with:

> synapse.app.homeserver - 210 - WARNING - phone_stats_home-0 - Error reporting stats: Invalid URI b''

The default endpoint URL now lives in a dedicated matrix_synapse_report_stats_endpoint_default variable, which group_vars/matrix_servers falls back to when synapse-usage-exporter is not enabled.

None of these flags exist in current Synapse:

- msc3266_enabled: MSC3266 support was stabilized in Synapse v1.153.0 and the room summary API is now always enabled

- msc4140_enabled: this was never a Synapse configuration setting in any released version. Delayed events have always been controlled by the `max_event_delay_duration` setting, which the playbook was emitting alongside the flag. The toggle is now named `matrix_synapse_delayed_events_enabled`.

- msc4429_enabled: MSC4429 support has not landed in any released Synapse version, so this flag never had any effect

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.
