eventLoop.timer(mode, interval) passes interval straight into
furi_ms_to_ticks() with no validation. For a periodic timer an interval
of 0 divides by zero in furi_event_loop_process_expired_timers()
(elapsed_time / timer->interval) and is counted as expired on every
event-loop pass, so a one-line script - eventLoop.timer("periodic", 0) -
pins the thread running the loop.
Reject interval <= 0 at the binding with a normal script-level error,
matching how the other js_app modules report bad arguments. The <= 0
check also covers negative values that would otherwise wrap to a huge
interval when cast to uint32_t.
