Addons: Improve code quality by using title as FC & sharing state via useAddonState

[ndelangen]

Telescoped off: #23288

What I did

• refactor the addon/actions to update the title due to it's own state
• refactor the addon/actions to update the title to use a FC
• refactor the addon/a11y to update the title to use a FC
• refactor the addon/controls to update the title to use a FC

How to test

• Addon actions should function as it was, but with a nicer looking number indicator
• Addon a11y should function as it was, but with a nicer looking number indicator
• Addon controls should function as it was, but with a nicer looking number indicator
