Notifications block list of positions and hamper fast trading#114

The current problem for users:

• all notifications are displayed on all pages and users have to dismiss each notification manually (this takes takes valuable time during high-volume trading circumstances)
• multiple notifications stack up and block the view of trading positions even on a 32” monitor (i.e. list of coins with open positions - I could share a screenshot)

The solution:

• offer a “Read All” feature that immediately dismisses ALL notifications
• maybe also offer Minimise feature that allows users to expand notifications later when required
