[Feature]: Update main screen app-icons layout

[L03TJ3]

Feature summary

Currently we support a horizontal single row icon list, that is scrollable on smaller-screens.
We want to update the layout to be supporting multiple rows, removing scrolling and opening up towards new added apps/widgets within the wallet.

Proposed solution

1. Two row with 4 icons max layout
2. up to 7 supported, a new app/widget/page that exceeds 7 will pop-up a 8th icon
   -- the 8th icon shows 'more...'
   -- clicking on the 'more' icon triggers the drawer that lists all remaining apps/widgets that are currently not shown yet

Acceptance criteria

• Updated layout
• No more scrolling on mobile
• Drawer functionality implemented
