fix: accept task input lists, omitted run and private user fields, and datetime usage dates

[apify-service-account]

Regenerates the models from the published OpenAPI specification (v2-2026-08-27T071624Z -> v2-2026-08-30T172245Z), which now describes the API's actual behavior after apify/apify-docs#2932. User-facing changes:

• Task.input, CreateTaskRequest.input, and UpdateTaskRequest.input also accept a list of objects, which the API stores and returns.
• DailyServiceUsages.date is a timezone-aware datetime instead of str.
• Run.general_access is optional - the API omits it for a run that follows the owner's account setting.
• UserPrivateInfo.plan, effective_platform_features, and is_paying are optional - GET /v2/users/{userId} responses don't carry them.

Previously, responses with any of these shapes failed model validation.

Closes #1040 (a manual test run of the same regeneration against a pre-merge bundle of the spec).
