Finalize all button styles in catalog

[minump]

Make all button styles consistent - all designs including active, hover, focus and disabled styles.

Change the a.button.button class focus style in capability view page. The button.button class focus style is similar to the zeplin style. Change a.button.button class focus style (has two border lines - see image) to match the button.button class focus style.

Check all pages and see if all button styles are consistent.
