Feat: custom config sliders

[Ajeet1606]

Add live timing strategy controls to the simulator.

Fixes: #11

• Added accordion-based sliders for debounce, throttle, rate limit, batching, and async-queue settings.
• Lifted configuration state into ExecutionSimulator and wired values directly into pacing hooks for immediate effect.
• Constrained desktop sidebar and timeline heights; sidebar scrolls independently so controls don’t distort canvas rows.
• Preserved the canvas’s original minimum row sizing.

Validation: npm run build and npm run lint pass.

@atapas please review.

Thanks for putting this together. I have a few comments:

1. The UI is missing some paddings, some aesthetic style part to be fixed

2. I would have Strategy settings section collapsed by default, User can expand it and set values. Hence recommending this portion to be visible always and rest of it should be expanded only to change the default values

3. Please test the changes in responsive mode too
