fix(dbapi): add PEP 249 Binary; bind Time as integer seconds

[sankalpsthakur]

Summary

Fixes #919.

Two DB-API / SQLAlchemy Core bind gaps:

1. Binary missing — SQLAlchemy LargeBinary calls dialect.dbapi.Binary(value) and raised AttributeError because clickhouse_connect.dbapi did not define it. Add Binary = bytes plus the other standard PEP 249 constructors (Date, Time, Timestamp, *FromTicks).

2. Time binds as HH:MM:SS — ClickHouse Time/Time64 store integer ticks (seconds for Time). format_query_value / format_bind_value left datetime.time and timedelta as bare string forms that the server rejects for Int32/Int64. Convert them to integer seconds so inserts and binds succeed.

Checklist

• Unit and integration tests covering the common scenarios were added
• A human-readable description of the changes was provided to include in CHANGELOG
• For significant changes, documentation in https://github.com/ClickHouse/clickhouse-docs was updated with further explanations or tutorials

Tests

• tests/unit_tests/test_driver/test_dbapi_types.py — Binary / PEP 249 constructors
• tests/unit_tests/test_driver/test_params.py — time/timedelta format_query_value, format_bind_value, finalize_query, server-side bind

Hi @sankalpsthakur, thanks for the work here but I am closing this PR because it combines two unrelated changes. The DB API constructor fix has been re-authored as a single PR with tests and a changelog entry. The time and timedelta binding changes are excluded because they corrupt Time64 values and break working server-side binds. That work will be handled separately.
