After Synapse's systemd health check passes, Traefik still needs
providers.providersThrottleDuration to register routes. Derive the
post-start delay from this setting (+1s for healthcheck polling gap)
instead of using a hardcoded value. Defaults to 0 when no Traefik
reverse proxy is used.

Switch the systemd ExecStartPost health check from docker exec + curl
to polling docker inspect for container health status. This piggybacks
on the container image's built-in HEALTHCHECK instead of duplicating it.

Also add a configurable container health interval (5s for Traefik setups,
15s otherwise) to speed up startup readiness detection without affecting
non-Traefik deployments.

Previously, we had a 10-second magical delay.

Now we first do a healthcheck to figure out when it really is up.
Then, we do the same 10-second magical delay to account for the time it
may take for a reverse-proxy (like Traefik) to pick up Synapse's routes.

The migrate service now declares Requires/After on matrix-synapse.service,
ensuring Synapse (and its transitive dependencies like Postgres and Docker)
are running before the migration triggers.

- https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html#enable_local_media_storage

We default it to `true`, keeping up with upstream and the old behavior.

s3-storage-provider users may set `matrix_synapse_enable_local_media_storage` to `false`
to disable local file caching.
This likely comes at the expense of some performance.

For matrix-media-repo users, it likely doesn't matter what this is set to,
as for a matrix-media-repo setup, all media-related API endpoints are
captured and forwarded to matrix-media-repo (before reaching Synapse).

This reverts commit c8c6a83ecc.

Synapse v1.142.0 is broken for Matrix Authentication Service deployments
that use a path-prefix (e.g. `/auth`) such as ours.

For such deployments, Synapse fails to contact MAS at the correct
introspection endpoint (it keeps hitting `/oauth2/introspect`, instead of `/auth/oauth2/introspect`)
and is not usable.

Currently problematic (leading to failures to start for Synapse) because of:
https://github.com/element-hq/synapse/pull/18759#issuecomment-3172744530

This defaults to true for end user comfort as it helps assure them the modules connection to the consumer is working or is definitively not working. (As far as i have been told it retries until success)
