fix: use setTimeout/setInterval from window object with correct TS type

[ghiscoding]

• newest version of @types/node and TypeScript is sometime throwing some errors
• I thought that we should always use setTimeout directly but its type is NodeJS.timeout type, however we should be using window.setTimeout with a return type of number instead since our project is always a Browser App hence the use of the window object
