[Bug] All changes are lost when switching the theme

[Biki-dev]

Description

When the theme is changed, all existing edits (shapes, images, etc.) are removed automatically. This results in loss of user work without any warning.

---

Steps to Reproduce

1. Add any shape or make any edits.
2. Open Settings.
3. Change the Theme.

---

Actual Behavior

• The theme changes, but all previously added shapes, images, and edits are removed automatically.

Expected Behavior

• Changing the theme should not delete user edits, or
• The app should warn the user that unsaved edits will be lost before applying the theme change.

---

Possible Solutions

1. Show an alert before changing the theme, informing the user that unsaved edits will be lost and allowing them to cancel or save first.
2. Automatically save the current state before applying the new theme so that user edits remain intact.

Additional Note

If the maintainers agree, I would like permission to work on this issue.
