I am new to Wealth-Lab. Does Wealth-Lab script run at the open (or close) of each bar or it can run in realtime on each tick?

In realtime, the script is executed when a new "bar" is added to the chart. The bar interval can be a tick if your streaming provider support it.

I would never recommend tick bars for trading using Wealth-Lab. There's too much overhead (post processing) to do that in real time. However, no matter what bar interval you use in real time, you should create a Workspace that uses the fewest Visualizers as possible - probably you only need the "Trades" visualizer for real time.

So it seems the script runs on 1-second chart, the script is executed every one second (assuming the stock is traded quite actively thus there is one bar for each second.)

Ticks and Seconds are basically not supported for live trading. No choice of second/tick scale in the Fidelity static data, no ability to run external data of those scales (e.g. IQFeed) in the Strategy Monitor.
