feat: allow raw automations to start disabled

[XiaoFeiCode]

Why

OpenHands/OpenHands#16567 adds a controlled test-run gate to automation creation. Raw bundle automations must be persisted as disabled before their first manual dispatch; creating them enabled and disabling them in a follow-up request leaves a race where a schedule or event can trigger untested code.

Summary

• add an optional enabled field to CreateAutomationRequest, defaulting to true for backward compatibility
• pass the requested state into the persisted Automation
• cover explicit disabled creation while preserving the existing default-enabled behavior

Validation

• uvx ruff check openhands/automation/router.py openhands/automation/schemas.py tests/test_router.py
• uvx ruff format --check openhands/automation/router.py openhands/automation/schemas.py tests/test_router.py
• python -m py_compile openhands/automation/router.py openhands/automation/schemas.py tests/test_router.py
• git diff --check

The targeted pytest could not be executed on Windows because litellm==1.93.0 publishes Linux wheels only and its source build requires an MSVC linker that is not installed. The test is included for Linux CI.
