This is a bit of a compatibility break.
The role was defaulting the Postgres password to `some-password` and we
auto-generate it now.

However, rebuilding both Postgres and this service should unify the
database credentials and the service configs to the new value.

This is an attempt at optimizing service startup.

The effect is most pronounced when many services are restarted one by one.
The systemd service manager role sometimes does this - for example when `just install-service synapse` runs.
In such cases, a 5-second delay for each Synapse worker service
(or other bridge/bot service that waits on the homeserver) quickly adds up to a lot.

When services are all stopped fully and then started, the effect is not so pronounced, because
`matrix-synapse.service` starts first and pulls all worker services (defined as `Wants=` for it).
Later on, when the systemd service manager role "starts" these worker services, they're started already.
Even if they had a 5-second wait each, it would have happened in parallel.

This probably never even worked anyway and was a leftover copy/paste
from some other role.

The docs (`docs/configuring-playbook-bridge-mautrix-wsproxy.md`) only
talk about `matrix_mautrix_wsproxy_hostname`, which was only used via
Traefik labels. The endpoint exposed via `matrix-nginx-proxy` (`/_matrix/wsproxy`)
hasn't been mentioned anywhere.

* Fix linting errors

* Cleanup after merge

* Correct outdated variable names

* Enable both Android and iMessage with wsproxy

* Restructure wsproxy service defs and nginx config

* Fix linter errors

* Apply suggestions from code review

* Fix comments for documentation, volumes and ports

* Correct mount syntax

* Complete network and traefik support for wsproxy

* Remove wsproxy data_path

* Fix wsproxy service definitions

* Actually include syncproxy service

* Remove wsproxy PathPrefix, it needs a subdomain

There's no setting in the iMessage bridge that allows a path.
Also don't bind port by default, wsproxy has no TLS.
Syncproxy should never expose a port, it's only internal.
