fix: support RN 0.85 hidden input absolute fill behavior

[anday013]

Motivation

• React Native 0.85 deprecated StyleSheet.absoluteFillObject which caused the OTP hidden TextInput to affect layout and make OTP cells move when filled.
• The fix must be applied in the source styles (not only dist) so all consumers get the RN 0.85-compatible behavior.

Description

• Remove ...StyleSheet.absoluteFillObject from hiddenInput in src/OtpInput/OtpInput.styles.ts and keep only the platform-visibility rules (opacity/color).
• Apply StyleSheet.absoluteFill directly in the rendered TextInput style array in src/OtpInput/OtpInput.tsx via style={[StyleSheet.absoluteFill, styles.hiddenInput, textInputProps?.style]} to ensure absolute overlay behavior on RN 0.85.
• Add a minimal regression test in src/OtpInput/__tests__/OtpInput.test.tsx that asserts the hidden input has absolute positioning and thus cannot affect OTP cell spacing, and update the snapshot accordingly.
• Regenerated build artifacts via the project tsc build so the produced dist output matches the source change.
• This change closes issue Support react native 0.85 #116.

Testing

• Ran npm test -- --runInBand -u and all tests passed with the snapshot updated successfully.
• Ran npm run ts:check (tsc --noEmit) and it completed without errors.
• Ran npm run build:prod (tsc -p tsconfig.prod.json) and the production build completed successfully.
• Verified there are no remaining absoluteFillObject occurrences in src or dist after the change.
