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.

These three roles have multiple variable prefixes each:
- kakaotalk: matrix_appservice_kakaotalk + matrix_appservice_kakaotalk_node
- telegram: matrix_mautrix_telegram + matrix_mautrix_telegram_lottieconverter
- synapse: matrix_synapse + matrix_synapse_customized + matrix_synapse_rust_synapse_compress_state
For each: renamed _docker_image* to _container_image* (and _docker_src*,
_docker_repo* where applicable), added deprecation entries in
validate_config.yml, updated group_vars references, and moved
deprecation tasks to the front of validate_config.yml.

`matrix_container_global_registry_prefix_override` may look similar to
the old `matrix_container_global_registry_prefix` variable
(removed in d6bf789710), but it's different.
The old `matrix_container_global_registry_prefix` variable was just a hardcode of `docker.io/` and roles that
needed to refer to `docker.io/` could use it. However, this was:
- not used by all roles, because some need another registry (not `docker.io/`)
- used only by roles within the playbook (`roles/custom`), not external roles
Overriding the old `matrix_container_global_registry_prefix` variable was rather pointless,
as it didn't cover everything.
The new `matrix_container_global_registry_prefix_override` variable, on the other hand,
lets you override the registry prefix for all components, regardless of whether they
use `docker.io/` or another registry by default.
This is useful to people who have somehow mirrored all container images to their own registry,
as it provides them with a single variable they can flip to influence the whole playbook.
This:
- brings consistency - no more mixing `_name_prefix` and `_registry_prefix`
- adds extensibility - a future patch will allow reconfiguring all registry prefixes for all roles in the playbook
We still have `_docker_` vs `_container_` inconsistencies.
These may be worked on later.
