[luiz-hfz]

Describe the bug

The elongated buttons do not have a mouse hover reaction like other buttons in the application.

To reproduce the bug

1. Go to 'https://jandig.app/'
2. Mouse over the 'login' button to verify correct behavior;
3. Hover the mouse over the 'go to camera' button to verify that the behavior does not occur.

Obs: The error is repeated on other buttons in the application

Expected behavior
When hovering the mouse over a button, its color should change.
