EVOC [EvoCardano] Token

EVOCARDANO.addLiquidity(uint256,uint256) (Evocardano.sol#443-458) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (Evocardano.sol#449-456)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

EVOCARDANODividendTracker.getAccount(address) (Evocardano.sol#532-575) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (Evocardano.sol#572-574)
EVOCARDANODividendTracker.canAutoClaim(uint256) (Evocardano.sol#596-602) uses timestamp for comparisons
Dangerous comparisons:
