Address feedback on zero-value raffle ticket operations

[Copilot]

What's new in this PR?

• Confirmed addRaffleTickets function allows zero-value operations and emits events for them

Why?

The bot reviewer suggested adding validation to prevent zero-value operations. However, emitting events for zero-value operations is intentional for debugging purposes - if a function is called with zero, that indicates a bug upstream and the event emission helps trace it.

No code changes were needed; the function already behaves as intended:

function addRaffleTickets(
    address user,
    uint256 amount
) external onlyRole(ADMIN_ROLE) {
    UserData storage userDataStorage = userData[user];
    userDataStorage.raffleTicketsBalance += amount;
    emit RaffleTicketsAdded(
        user,
        amount,
        userDataStorage.raffleTicketsBalance
    );
}
