Refactor/actions reserve overview

[AGMASO]

General Changes

• Refactored the Supply and Borrow actions on the reserve-overview page to fully use the SDK for calculating health factor previews and for building the transaction to be sent. • Special cases for wrapped tokens (DAI/sDAI) and USDT resets are all covered and tested.

• This PR also includes the refactor of Withdraw and Repay (added here for future use in the dashboard page).

Developer Notes

• For testing purposes, you can access the Supply SDK and Borrow SDK in the reserve-overview page. • You can access the Withdraw SDK and Repay SDK in the supplied position view and borrowed position view respectively.

• NOTE: Major issue blocking the release of the Repay SDK flow: I have tested that the SDK’s Repay action does not support aToken repayments. This means we cannot repay debt using collateral; only ERC-20 tokens from the wallet are supported.
