UI/UX in awards and member_management.py

[rushilrawat]

Description:

1. The ribbon on top is too big
2. The boxes need to be fixed (size, spacing)
3. The right margin is smaller in most cases — needs balancing
4. The button size needs to be fixed (too small or cramped sometimes)

Overall Improvement:

• A more cleaner and lighter UI is needed in general
• Proper padding, margins, and proportional button sizing
• Header ribbon height should be reduced for a modern feel
• More breathing space around boxes and tables
