SCD staging tables dedup function added

[eduardo-nercolini]

Overview

We have identified issues with the intermediate scd_claimable_balances and scd_liquidity_pools models creation and testing due to duplicate data coming from the sources. To temporarily mitigate the problem while it is being investigated and a permanent solution is proposed, we have implemented a dedup function in the staging models that this tables pull from. This is to prevent downstream model creation and testing failures stemming from this issue.

Key changes

• row_number window function and qualify function added to stg_claimable_balances and stg_liquidity_pools to remove duplicated data to downstream models.
