Serving at a path other than `/` doesn't work well yet.

We were mounting our own configuration to
`/usr/share/nginx/html/config.json`, which is a symlink to
`/tmp/config.json`. So we effectively mount our file to
`/tmp/config.json`.

When starting:

- if Hydrogen sees a `CONFIG_OVERRIDE` environment variable,
  it will try to save it into our read-only config file and fail.

- if Hydrogen doesn't see a `CONFIG_OVERRIDE` environment variable (the
  path we go through, because we don't pass such a variable),
  it will try to copy its bundled configuration (`/config.json.bundled`)
  to `/tmp/config.json`. Because our configuration is mounted as read-only, it will
  fail.

In both cases, it will fail with:

> cp: can't create '/tmp/config.json': File exists

Source: 3720de36bb/docker/dynamic-config.sh

We work around this by mounting our configuration on top of the bundled
one (`/config.json.bundled`). We then let Hydrogen's startup script copy
it to `/tmp/config.json` (a tmpfs we've mounted into the container) and use it from there.

This may proof useful to someone in the future.

We've had it on `matrix-nginx-proxy` before, but
our initial support for Traefik did not include any of these security
headers.

Previously, we had to run it at a subpath, like `/synapse-admin`.

We can now dedicate a whole domain and the `/` path to it, should we
wish to do so.

Update postmoogle 0.9.12 -> 0.9.13

Regression since 3d9aa8387e

* live SSL certificates reload on file changes (e.g., on automatic certs renewal)
* print all errors when trying connection to an SMTP server

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2474

Seems like this affected all "own webserver" deployments, which required
port exposure.

`playbook-managed-traefik` and `playbook-managed-nginx` were not affected.

Update coturn 4.6.1-r1 -> 4.6.1-r2

restore borg prefixes

Supersedes https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2472

It's probably unnecessary, as this user is only used in the borg container
internally, but.. It doesn't hurt to set it to `matrix`.

fix: missing endif

* fix: only add element related entries to client well-known if element is enabled

* Fix matrix-base/defaults/main.yml syntax
