* fix(automations): start scheduler in headless serve mode
* Trigger initial catch-up check for headless scheduled automations
Headless serve never receives a renderer-ready IPC, which previously
prevented the initial catch-up pass of due scheduled automations from
running on startup. Checking for the presence of a headless dispatcher
allows starting the evaluation pass immediately.
Additionally, refactor the corresponding test to use fake timers for
better reliability and deterministic assertions.
