fix(gateway): accept finalize kwarg in all platform edit_message overrides

stream_consumer._send_or_edit unconditionally passes finalize= to
adapter.edit_message(), but only DingTalk's override accepted the
kwarg. Streaming on Telegram/Discord/Slack/Matrix/Mattermost/Feishu/
WhatsApp raised TypeError the first time a segment break or final
edit fired.

The REQUIRES_EDIT_FINALIZE capability flag only gates the redundant
final edit (and the identical-text short-circuit), not the kwarg
itself — so adapters that opt out of finalize still receive the
keyword argument and must accept it.

Add *, finalize: bool = False to the 7 non-DingTalk signatures; the
body ignores the arg since those platforms treat edits as stateless
(consistent with the base class contract in base.py).

Add a parametrized signature check over every concrete adapter class
so a future override cannot silently drop the kwarg — existing tests
use MagicMock which swallows any kwarg and cannot catch this.

Fixes #12579
