getClaimableOAS is included claimed oas value

[Tsuyoshi-Ishikawa]

getClaimableOAS is included claimed oas value.
I think claimableOAS must not be include claimed oas.

Modification

function claim(uint256 amount) external {
        if (amount == 0) revert NoAmount();

        ClaimInfo storage originalClaimInfo = claimInfo[originalClaimer[msg.sender]];
        uint256 currentClaimableOAS = getClaimableOAS(originalClaimer[msg.sender]); // modified

function getClaimableOAS(address original) public view returns (uint256) {
...
         if (amount > originalClaimInfo.amount) {
            // return originalClaimInfo.amount;
            return originalClaimInfo.amount - originalClaimInfo.claimed; // modified
        }

After that

We have to modify oasys-pos-fe after this modifications.
