Low contrast when entering access code during sync setup

Thank you for making this app.

I recently set it up on iPhone with latest iOS 26.7, Joplin app version 13.7.5 When it comes to setting up sync with Dropbox the field to enter the code is hard to see even though the text is there.

By adding different background color that is of higher contrast it would be easier to see improving the UX. Below is a screenshot of how it looked on my phone.
