Pull request overview

This PR removes the generated SigninService/SignoutService OpenAPI client surfaces and the associated session-cookie management logic from the write client, leaving only WriteService as the exposed service.

Changes:

• Delete signin_service.py and signout_service.py and stop re-exporting them from package/service/client __init__.py modules.
• Remove session-cookie lifecycle helpers from write_client/rest.py.
• Refactor _sync/api_client.py to drop cookie handling and sign-in/sign-out behavior (but currently leaves a broken import that must be fixed).

influxdb_client_3/write_client/client/_base.py:72

• auth_basic / username / password support appears to have been removed, but passing these kwargs will now be silently ignored, which can lead to confusing auth failures for existing consumers (especially since InfluxDBClient3 forwards **kwargs into the write client). Consider explicitly rejecting these removed options (or emitting a clear deprecation/error) so users fail fast with actionable guidance.

        # defaults
        self.auth_header_name = None
        self.auth_header_value = None
        # by token
        if token:

influxdb_client_3/write_client/client/_base.py:72

• Removed auth modes (auth_basic and username/password) are now silently ignored if a caller still passes them via **kwargs, which can lead to confusing, unauthenticated requests. Since this PR removes support, it would be safer to fail fast with a clear ValueError when these kwargs are provided (non-empty/true).

        self.auth_header_name = None
        self.auth_header_value = None
