[FEAT] Add a Reset button to clear all editor tabs back to default state

[devendra-w]

Problem

Once users start editing, there's no quick way to clear all editors and start fresh without manually deleting all code.

Expected Behaviour

• A Reset button in the toolbar
• Clicking it shows a confirmation dialog
• On confirm, clears HTML, CSS, and JS editors back to empty/blank template state

Implementation Notes

• Add a reset handler that calls setCode with empty strings
• Show a window.confirm() or a simple modal before resetting
• Clear localStorage autosave on reset

Difficulty

Hi @Debmallya-03! I'd love to work on this. I'll add a reset handler that clears all editor state, show a confirmation dialog before resetting, and also clear the localStorage autosave. I'm already familiar with the codebase from previous contributions. Can I be assigned?
