improvement: handle rate interest

[azurwastaken]

Current Behavior

currently we retrieve computed position amount only once when encountered. This can lead to false negative due to rate interest.

Expected Behavior

Find a way to update position amount over time. No need to update it too frequently because rate impact are not that big.

Possible Solution

• Find a way to get latest rate_accumulator and nominal_debt from emitted event to compute amount locally and not calling RPC. (Favourite)

or

• Call get_amount on each indexed position every N seconds/minutes/hours and update them.
