Feat: “Run now” on a schedule

[leobrqz]

Idea: Add a “Run now” (or play) action on each schedule row.

It runs that schedule’s script once immediately, reusing the same capture path and logging as a normal run (status “started” / “exited”, same history and run log).

Reuse _execute_scheduled_run (or a variant) so behavior and logs stay consistent.

Useful for testing a schedule or doing a one-off run without creating a new schedule.
