Good First Issue
Description
The Review ahead dialog
- Add a title "Review ahead".
- Replace the description with "Review cards due in the next:".
- Add a unit "day"/"days" to the box.
- Replace "OK" with "Create".
- If the resulting filtered deck is empty (i.e., no cards match the criteria), a red warning should appear and the button should be disabled, instead of an error dialog (see reference).
- Show a warning when the input is invalid, limit the digits, and prevent leading zeros, like in https://github.com/ankidroid/Anki-Android/pull/20520, except without input steppers.
