PinCodeInput class
A configurable PIN input display that shows the current PIN entry state.
Does NOT include a software keyboard — pair with PinNumericKeypad or rely on the platform keyboard.
Supports two visual styles via PinInputStyle:
- PinInputStyle.boxes: individual bordered boxes, each showing a bullet when filled. Suited for full-page setup/change screens.
- PinInputStyle.circles: small circles that fill in when a digit is entered. Suited for compact dialog overlays (user switching).
The number of indicators is driven by pinLength (default 5).
