The Studio button box dialog now shows the proper label for related fields. This helps users choose the right field more confidently and avoids confusion when configuring forms.

The value displayed for the related field in the new button box dialog was not the correct one.

A new automated check confirms that spreadsheet images using access tokens can be deleted correctly. This helps prevent regressions that could leave unwanted images behind in spreadsheet records.

This commit adds a test to ensure image with tokens can be properly deleted.

This fixes an automated bank reconciliation tour that could fail when a tax column appeared and the validate button was not ready yet. The update waits until the button is clickable, reducing false test failures and improving confidence in accounting workflows.

The tour may sometimes fail, because the column of taxes appear,

We just add a step so the button is clickable before clicking on it.
