Related to #2536

• 1. 'Connect to a wallet' button's boarder has a light boarder and seems like have a different boarder radius
  
  
  

• 2. Profile page: 'Connect to a wallet' button is too wide
  

• 3. Text in the network selector is almost invisible in the dark mode
  

• 4. Networks in the selector are not aligned
  

• 5. Token lists exceed the modal area
  

• 6. Arrow before' Add a send' field has too bold boarder + center-aligned
  
  

• 7. Naming is inconsistent: 'Add a send' and 'Remove recipient'. I think, we need to use 'recipient' for both labels (or at least 'send' for both, as it is currently on Prod)
  

• 8. Too big tooltips
  

• 9. Account Icon on the 'Confirm' modal is too small
  
  -The same is on the 'Claim' page
  

• 10. Network selector exceeds right screen boarder in mobile devices
  

• 11. Network selector is opened 'on hover' event instead of the 'on-click' as we currently use on Prod. So when I press on the network selector twice, it remains opened until I remove a mouse from it. Will we leave it as it is or change to the behavior we currently use?

• 12. Sometimes I can't open the network selector after a network changing in a mobile view
