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.

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

When no experimental features were enabled (e.g. Matrix RTC and Matrix Authentication Service both disabled), the generated homeserver.yaml contained `experimental_features: null`, which Synapse v1.157.0+ does not tolerate and crashes on startup.

The `experimental_features` configuration is now constructed via a dedicated `matrix_synapse_experimental_features` variable (split into `_default`, `_auto` and `_custom`, as is customary), which always yields a mapping (potentially an empty one).

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.

A single prefix-level catch in matrix_playbook_migration covers all
renamed bridge variable prefixes at once. It always runs (unlike the
per-role validate_config tasks, which only run when a role is enabled),
so a stale old-style _enabled variable cannot silently disable a bridge.

Renames the matrix_mautrix_SERVICENAME_* placeholders in the common
mautrix bridges guide to matrix_bridge_mautrix_SERVICENAME_*, and fixes
prose in the matrix-bridge-steam role that referred to the old variable
prefix and to a misspelled (underscore-styled) systemd service name.
