* Make interface hidden behind proxy by default

* Remove expose option and replace with http_bind_port

Reasoning: This is a similar binary trigger but allows to bin not on all interfaces

* Clarify maubot admin purpose

* Remove unnecessary edif

* Extend docs to prevent common misconceptions

* Make http_bind_port singular, do not allow multiple values

* Make optional again

Make use of `example.com` more consistent (replace `DOMAIN`) and simplify Caddy 2 config. Remove Caddy 1 config since Caddy 1 is long past EOL.

Synapse no longer describes the stats as anonymized since the `server_name` is included.

This does 2 things:

- it fixes the syntax for `matrix_id`. Starting strings with `@` is
  invalid YAML, so such strings need to be wrapped in single or double
  quotes
- it makes use of the `matrix_domain` variable instead of hardcoding the
  domain name. This should be more and mistake-proof (typos or people
  mistaking their domain - matrix. vs base domain)

Adding the defaults in addition to template, switching YOUR_DOMAIN to {{ matrix_domain }}, and giving example of the two combined, as the playbook gives a warning about things being defined twice, so only using the last one in the vars.yml

Copy/Pasting from docs/configuring-playbook-bridge-mautrix-facebook.md but with the relevant variable names changed to add turning on encryption and a puppet admin.

Adding a bit on how to bind the synapse ports if the webserver isn't in the same docker network, or on a different machine.

Logging in from the IP address is no longer always enough, but 2FA seems to work eventually

Fixup for #1877.

Based on mautrix-whatsapp, as that's what the bridge software is based on.

This is a poor way to do things though. It may break again in the future.
matrix-registration is a poorly maintained project and should likely be removed from the playbook.
