Remove Placeholder Zero in Number Fields During Input

[pmjanus]

[Bug]

🐛 Description
When users interact with number fields in write functions, the placeholder "0" remains visible and interferes with user input, creating confusion and potential data entry errors. The placeholder should clear when users begin typing.

📋 Current Behavior

• Number fields display "0" as a placeholder
• When users start typing, the "0" remains in the field
• Creates confusion during data entry
• Affects all number fields in write functions

🎯 Expected Behavior

• Number field shows "0" as initial placeholder
• Placeholder completely disappears when user starts typing
• User sees only their input numbers

📝 Steps to Reproduce

1. Navigate to any write function with number fields
2. Observe the "0" placeholder in the number field
3. Start typing numbers
4. Notice the "0" remains alongside user input

🧠 Tasks

• Review current number field implementation
• Modify placeholder behavior to clear on focus/input
• Test placeholder removal across different input scenarios
• Verify no impact on form validation
• Update field value handling to properly manage empty states
• Cross-browser testing of the fix

💡 Technical Notes

• Affects number input fields in write functions
• May require modifications to input event handlers
• Consider empty state handling

🔍 Impact

• Improves data entry accuracy
• Enhances user experience
• Reduces potential for input errors

📊 Priority
Medium - Affects user experience but doesn't prevent functionality
