fix: accept **kwargs in Bool.__init__ for SQLAlchemy type compatibility

[Bahtya]

Problem

Using Bool from clickhouse_connect.cc_sqlalchemy.datatypes.sqltypes in SQLAlchemy ORM models fails with:

TypeError: Bool.__init__() got an unexpected keyword argument _create_events

This makes the Bool type unusable in ORM models.

Root Cause

SQLAlchemy internally copies/adapts types by calling __init__(**kwargs) with additional keyword arguments like _create_events. The Bool.__init__ only accepts type_def, so these extra kwargs cause a TypeError.

Solution

Accept **kwargs in Bool.__init__ and forward them to SqlaBoolean.__init__(self, **kwargs).

Fixes #705

@joe-clickhouse Thank you for the guidance. I see the CLA needs to be signed through the web interface at the cla-assistant.io link. I'll complete that step shortly. The CHANGELOG entry is already added. Apologies for the delay!

[joe-clickhouse]

@Bahtya hope you don't mind, but I moved the changelog note to the unreleased section and added a minimal regression test. Thanks again for the work!

Looks good!
