-Here, `deposits` indicates the total amount of collateral deposited. `get_collateral_valuation_price` takes in the total deposits in the protocol and interpolates between (`0`, `rate_discount_inital`) and (`deposits_endpoint`, `rate_discount_final`) to linearly caclulate the discount at `deposits`. As a note, this function scales down the price depending on the provided discount and deposit inputs, but it does not alter the confidence.
