Stellar add security contract field

[CoveMB]

Fixes #440 (for Stellar only)

• Add input UI component to capture security info
• Update info type for Stellar
• Add security info for AI agent
• Add contract documentation for Stellar contract builder
• Add print of contract documentation ( here security info) for Stellar
• Add test for printing documentation

@brozorec @ozgunozerk Would this be the appropriate placement for the security contact comment (and possibly other contract level comments)?

Following our docstring practice, I suggest this goes like so:

/// SPDX-License-Identifier: MIT␊
/// Security Contact: [email protected]␊
/// Compatible with OpenZeppelin Stellar Soroban Contracts ^0.2.0␊
#![no_std]␊
