SERVICES-1379: compute undistributedBoostedRewards

[dragos-rebegea]

compute undistributedBoostedRewards including unclaimed rewards

Reasoning

• Currently undistributedBoostedRewards only returns the amounts that has been collected using collectUndistributedBoostedRewards. Since undistributedBoostedRewards should contains also the uncollected, we should compute the value.

Proposed Changes

• Calculates the total undistributed boosted rewards for a given smart contract address (scAddress) up to the current week (currentWeek) by first fetching the undistributed boosted rewards and the last week when these rewards were collected. If the period of unclaimed weeks is more than the maximum number of weeks a user can claim, it only considers the rewards from the last USER_MAX_CLAIM_WEEKS. It then calculates the rewards remaining to be distributed for each week starting from the week after the last collection up to the week derived from subtracting the maximum claim weeks from the current week. The total of these remaining rewards is then added to the previously fetched undistributed boosted rewards to get the total amount.

How to test

• Test by providing a smart contract address (scAddress) and the current week (currentWeek). Check that the function returns the correct total undistributed boosted rewards.
• Test the edge case where the starting week is later than the ending week, the function should return the undistributed boosted rewards without calculating the remaining rewards.
