[Edge Case] Handle zero-address in whitelist and project creation

[AbelOsaretin]

Description

The contract doesn't validate that addresses are non-zero. While Soroban may prevent zero addresses, explicit validation would improve clarity.

Current Code Location

project_registry/src/lib.rs:26-33, project_registry/src/lib.rs:35-69

Recommendation

• Add zero-address checks where appropriate
• Document address validation requirements
• Consider using address validation utilities
• Add tests for zero-address scenarios

Severity

Low — Input validation.
