Running `just add-inventory-host example.com 1.2.3.4` (or
`make add-inventory-host domain=example.com ip=1.2.3.4`) adds a new
host to the inventory, creating inventory/hosts and
inventory/host_vars/matrix.DOMAIN/vars.yml from the example files,
with strong secrets generated automatically.

Existing configuration is never overwritten. The command refuses to
run if the host is already in the inventory, so it can also be used
for adding more hosts later.

Based on the idea proposed in

The sygnal container images (since v0.16.0) hardcode a HEALTHCHECK which
relies on curl, but the image does not include curl, so the healthcheck
can never pass. See https://github.com/element-hq/sygnal/issues/326

This unblocks upgrading sygnal past v0.15.1.

Remove matrix-registration-bot

This is a major upgrade which performs a one-way database migration
and removes LDAP support upstream.

The continuwuity.toml.j2 template is re-synced with the v26.6.1 example
config. Notably, registration_token is now only rendered when non-empty,
because v26+ refuses to start when it is set to an empty string.
