fees in ``FeeCollector.sol::_initializeFeeTypes()`` are higher

makriss

Summary

feeTypes[6] and feeTypes[7], for Buy/Sell Swap Tax and NFT Royalty Fees are 2% but they take 20%

Vulnerability Details

FeeCollector.sol::_initializeFeeTypes(): https://github.com/Cyfrin/2025-02-raac/blob/main/contracts/core/collectors/FeeCollector.sol#L330

the Percentage calculation represented by BASIS_POINTS = 10000 which is 100%
https://github.com/Cyfrin/2025-02-raac/blob/main/contracts/core/collectors/FeeCollector.sol#L91

so 10000 = 100% and 1000 = 10% and 100 = 1% and 10 = 0.1%

but here 1000 represented by 1% and 500 by 0,5% which is false

// Buy/Sell Swap Tax (2% total)
feeTypes\[6] = FeeType({
veRAACShare: 500, // 0.5%
burnShare: 500, // 0.5%
repairShare: 1000, // 1.0%
treasuryShare: 0
});
​
// NFT Royalty Fees (2% total)
feeTypes[7] = FeeType({
veRAACShare: 500, // 0.5%
burnShare: 0,
repairShare: 1000, // 1.0%
treasuryShare: 500 // 0.5%
});

Fee shares for fee type 6 and 7 inside FeeCollector do not total up to the expected 10000 basis points, this leads to update problems, moreover they are 10x the specifications
