The backup pages' primary buttons (Add location, Save changes) and Delete
location button used a local gradient + glow in backup.css, so they didn't
match the flat solid-accent buttons on the config page. Add .backup-primary-btn
and .backup-danger-btn to the shared nebula button groups in themes.css
(.btn-primary / .btn-uninstall) so they get the same solid accent/danger fill
and hover with !important across themes, and drop the local gradient/shadow/lift
from backup.css. Top-right and bottom-of-page backup buttons now match config.
