Ap/grants active to inactive

[adityapat24]

ℹ️ Issue

Closes #137

📝 Description

Added functionality so that the status of grants are automatically updated from active to inactive if their timeline has expired

Briefly list the changes made to the code:

1. Added a call to a makeGrantsInactive method when fetching all grants to update the status
2. makeGrantsInactive updates the status to be inactive and returns the entire grant back
3. List of updated grants added in all grants and returned to the user
4. Updated grant controller to have an inactivate route

✔️ Verification

Wrote tests for new makeGrantsInactive method

I would make the makeGrantInactive method just take in one grantId and in the outer method loop over the array you created. When you do it as an array in makeGrantInactive one grant erroring causes all the other grants to not be processed

I fixed it myself
