🔒 Fix insecure randomness in Smart Pick Generator

[artosien]

🎯 What: Replaced the vulnerable Math.random() usage for generating final "Smart Pick" lottery numbers with the cryptographically secure window.crypto.getRandomValues().

⚠️ Risk: Math.random() is not cryptographically secure, which means the sequence of generated numbers could potentially be predicted. In the context of a lottery number generator, this compromises the fairness and unpredictability of the "Smart Picks".

🛡️ Solution: Switched to generating random 32-bit integers using window.crypto.getRandomValues(new Uint32Array(1)) and scaling them to a [0, 1) range. This ensures the randomness is secure and not easily predictable while maintaining the necessary distribution across the active game's range.
