Issue #1: Cannot Paste Addresses in Input Fields

[tjayrush]

Priority: BLOCKING
Component: Input System

Description:
Address input fields do not support clipboard operations, making it impossible to enter 0x addresses practically.

Steps to Reproduce:

1. Navigate to Project Manager → + New Project
2. Try to right-click in address field
3. Try Ctrl+V to paste an address

Expected Behavior:

• Right-click shows context menu with paste option
• Ctrl+V pastes clipboard content
• Users can easily input 40-character 0x addresses

Actual Behavior:

• Right-click does nothing (no context menu)
• Ctrl+V does nothing (paste disabled)
• Users must manually type 40-character hex addresses

Impact: Users cannot reasonably enter Ethereum addresses, making the app unusable for its primary purpose.

Technical Notes: This affects all address input fields in the application.
