Version 2.4.0 (build 20400)

* Android: targets SDK 34 and requires minimum SDK 26.
* Upgrade build tools and dependencies.
* Ensure history doesn't become unreadable when an invalid card is read (#26).
* Update App Icons:
  * Add adaptive and monochrome icons on Android.
  * Add dark and tinted icons on iOS.
* Show Flutter builtin open-source license page instead of handcrafted HTML.

There are still remaining issues with iOS. We will fix it in later releases.
