Add Standard Elliptic Curve Parameter Viewer

[AprilNEA]

Description:

Implement a tool to display parameters of standard elliptic curves commonly used in cryptography.

User Story:

As a developer working with ECC, I want to quickly reference standard curve parameters so that I can verify my implementation against known standards.

Features:

• Display parameters for P-256, P-384, P-521, secp256k1, secp256r1, etc.
• Show curve equation, prime field, generator point, and order
• Search/filter functionality for curves
• Export curve parameters in various formats

Acceptance Criteria:

• Support at least 10 standard curves
• Display all essential curve parameters
• Responsive design for mobile and desktop
• Export functionality works correctly
