Matches the earlier Python -> Go rewrites of the other mautrix-* bridges.

The bridge is now a Go binary with upstream-handled automatic database and
config migration on first start, so in-place upgrades on Postgres should
Just Work for users on the defaults. The lottieconverter sidecar container
is gone (bundled upstream), and the public web-based login endpoint is
gone (login happens inside Matrix now).

Upstream v0.2604.0 has a known bug in the legacy SQLite migration that
can corrupt data. The role detects legacy Python-bridge SQLite databases
(via the `telethon_sessions` table signature) and refuses to upgrade,
pointing users to switch to Postgres (playbook-managed pgloader migration)
or wait for the next upstream release. The guard is isolated in its own
`validate_config_sqlite_legacy_migration_bug.yml` so it can be deleted
cleanly once upstream fixes the bug.

Removed variables (all caught by the deprecation check in
`validate_config.yml` with actionable rename/removal hints): the entire
`_hostname` / `_path_prefix` / `_scheme` / `_public_endpoint` /
`_appservice_public_*` / `_container_labels_public_endpoint_*` /
`_container_http_host_bind_port` family (web login endpoint is gone);
`_bot_token` (old-style relaybot is gone, use the common bridgev2 relay
mode); `_filter_mode` (dropped upstream); `_bridge_login_shared_secret_map*`
(use Appservice Double Puppet); `_username_template`, `_alias_template`,
`_displayname_template` (templates moved under `network:`, new Go-template
syntax, exposed via `_network_displayname_template`); all
`_lottieconverter_*` variables; `_appservice_database` (renamed to
`_appservice_database_uri`).

Added playbook-time validation that catches legacy permission values
(`relaybot`, `puppeting`, `full`) in the fully-merged config (so overrides
via `matrix_mautrix_telegram_configuration_extension_yaml` are caught too),
with a mapping hint in the error message.

Other notes:

- The legacy sqlite->postgres relocation of `{base_path}/mautrix-telegram.db`
  to `{data_path}/mautrix-telegram.db` now happens BEFORE the pgloader
  migration step, so users who flip to Postgres as part of this upgrade
  get their data imported correctly.
- The Ketesa managed-user regex for the telegram namespace is updated to
  match both regular IDs and the new `channel-<id>` form used by bridgev2.
- `matrix_playbook_migration_expected_version` bumped to v2026.04.24.0,
  with a new breaking-change entry pointing at the CHANGELOG section.

* Add matrix_bridges_msc4190_enabled flag for using msc4190 on supported mautrix bridges.

* Apply to_json to msc4190 in mautrix configs

* Add | to_json to mautrix bridge registration io.element.msc4190.

* require matrix_synapse_experimental_features_msc3202_device_masquerading_enabled for matrix_bridges_msc4190_enabled

* Also add msc4190 support for mautrix-telegram

We do not let bridges update config files, so generation cannot happen.
We don't want the bridge to manage the config file anyway.

This paves the way for installing other roles into `roles/galaxy` using `ansible-galaxy`,
similar to how it's done in:

- https://github.com/spantaleev/gitea-docker-ansible-deploy
- https://github.com/spantaleev/nextcloud-docker-ansible-deploy

In the near future, we'll be removing a lot of the shared role code from here
and using upstream roles for it. Some of the core `matrix-*` roles have
already been extracted out into other reusable roles:

- https://github.com/devture/com.devture.ansible.role.postgres
- https://github.com/devture/com.devture.ansible.role.systemd_docker_base
- https://github.com/devture/com.devture.ansible.role.timesync
- https://github.com/devture/com.devture.ansible.role.vars_preserver
- https://github.com/devture/com.devture.ansible.role.playbook_runtime_messages
- https://github.com/devture/com.devture.ansible.role.playbook_help

We just need to migrate to those.

Not doing {% if matrix_admin %} checks in the YAML also fixes some issues
with indentation being incorrect sometimes.

This should be backward compatible, except for mautrix-signal's case
where `matrix_mautrix_signal_bridge_permissions` previously existed
as a string, not a dictionary. `tasks/validate_config.yml` will catch
the problem an even provide a quick fix.

I don't use this bridge, so this is completely untested.

If a service is enabled, a database for it is created in postgres with a uniqque password. The service can then use this database for data storage instead of relying on sqlite.

Fixes #586 (Github Issue)

We log to journald anyway. There's no need for double-logging.

It should not that matrix-synapse logs to journald and to files,
but that's likely to change in the future as well.
Because Synapse's logs are insanely verbose right now (and may get
dropped by journald), it's more reliable to have file-logging too.

As Synapse matures and gets more stable, logging should hopefully
get less, we should be able to only use journald and stop writing to
files for it as well.

The goal is to move each bridge into its own separate role.
This commit starts off the work on this with 2 bridges:
- mautrix-telegram
- mautrix-whatsapp

Each bridge's role (including these 2) is meant to:

- depend only on the matrix-base role

- integrate nicely with the matrix-synapse role (if available)

- integrate nicely with the matrix-nginx-proxy role (if available and if
required). mautrix-telegram bridge benefits from integrating with
it.

- not break if matrix-synapse or matrix-nginx-proxy are not used at all

This has been provoked by #174 (Github Issue).

Use Jinja2 lstrip_blocks option in templates to ensure consistent
indentation in generated files.

As suggested in #63 (Github issue), splitting the
playbook's logic into multiple roles will be beneficial for
maintainability.

This patch realizes this split. Still, some components
affect others, so the roles are not really independent of one
another. For example:
- disabling mxisd (`matrix_mxisd_enabled: false`), causes Synapse
and riot-web to reconfigure themselves with other (public)
Identity servers.

- enabling matrix-corporal (`matrix_corporal_enabled: true`) affects
how reverse-proxying (by `matrix-nginx-proxy`) is done, in order to
put matrix-corporal's gateway server in front of Synapse

We may be able to move away from such dependencies in the future,
at the expense of a more complicated manual configuration, but
it's probably not worth sacrificing the convenience we have now.

As part of this work, the way we do "start components" has been
redone now to use a loop, as suggested in #65 (Github issue).
This should make restarting faster and more reliable.

It used to allow user to logging with their own account to the bot
