InputOtp | KeyboardEvent.code --> KeyboardEvent.key (& fix bugs on Android browsers not supporting .code)

[Perfect03]

Describe the bug

A bug was noticed in the InputOtp component on Android Chrome — this modern mobile browser does not provide event.code. As a result, it’s impossible to delete characters entered into Input (the event.code === 'Backspace' check fails). Most likely, similar bugs exist across other components.

Reason for not contributing a PR

• Lack of time
• Unsure how to implement the fix/feature
• Difficulty understanding the codebase
• Other

Other Reason

Migrating all checks from event.code to event.key across the codebase fixes issues in modern browsers and makes the code more consistent.

If this PR gets rejected, I’ll of course submit a small bugfix for InputOtp (just a few lines). However, it would be better to apply the event.code → event.key migration across the entire codebase for consistency.
