fix(input): align border styling with textarea and add input best practices

- Change default border from border-primary to border-border-primary for consistency with Textarea
- Add autoComplete='off' to disable browser autocomplete
- Add spellCheck='false' for text inputs to prevent red underlines
- Add autoCapitalize='none' for email/URL inputs
- Update tests to match new border styling expectations
- Simplify variant logic while maintaining error precedence
