Critical fix: Comprehensive input field text visibility

- Fixed all text input visibility issues across the platform
- Added explicit color styles for all input types (text, email, password, etc.)
- Added -webkit-text-fill-color for Safari/Chrome compatibility
- Fixed placeholder text visibility
- Added proper focus and disabled states
- Fixed autocomplete color overrides
- Created reusable Input/Textarea components
- All inputs now have white background with dark text guaranteed
- Resolves issues where users could only type 1-2 letters or see nothing
