feat(scenarios): add timeoutSeconds to scenarios and steps

- add timeoutSeconds field to scenario and step entities
- add timeoutSeconds to create/update DTOs for scenario and step
- enforce timeout via scheduler: abort run if step exceeds limit
- expose timeoutSeconds in MCP create/update scenario and step tools
- add client-side type, API, i18n, and form support for timeoutSeconds
- add integration tests for timeout persistence via REST and MCP
