Test plan:
1. Go to Administration
2. Click on Budgets
3. Add a new bdget and check the 'Lock budget' box
4. Click on the 'Inactive budgets' tab
5. Note that 'Locked' is displayed in green
6. Apply patch
7. Compile the sass files (setup detailed here:https://wiki.koha-community.org/wiki/Working_with_SCSS_in_the_OPAC_and_staff_interface ) by running:
yarn build

8. Refresh the page and notice the 'Locked' text is now red, and there
is a lock icon to the left of the text. There is a space between the
lock icon and the 'Locked' text.
