Backup Limits, Translations, and Icon Editor Fix

SupaSidebar 1.3.2 adds automatic backup limits, expands translations, and fixes the icon editor's appearance in colored Spaces.

Improvements

• Choose How Many Backups to Keep: Automatic Backups now lets you keep 1, 5, 10, 25, 50, or 100 backups, with 10 as the default. Older automatic backups are removed only after a new backup saves successfully. Manual exports are left alone.
• More Translated Text: Expanded translations across the 11 supported non-English languages, including Spaces, backup settings, onboarding, sidebar dialogs, and notifications. Existing translations are preserved.

Bug Fixes

• Readable Icon Editor: Fixed the white-on-white icon picker in Spaces that use white sidebar text. The icon popover and editor sheet now use a matching light or dark appearance.
