DefiSaver integration: show user's safe position if available

[bout3fiddy]

If a user with a defisaver position connects to lend.curve.fi or crvusd.curve.fi, then impersonate a different wallet address (the safe address)

Defisaver API information:

API: https://app.defisaver.com/safe/all-wallets?account=[address]&network=[chainId]

Example: https://app.defisaver.com/safe/all-wallets?account=0xEA57Dc30959eb17c506E4dA095fa9181f3E0Ac6D&network=1

It returns both the legacy DSProxy wallets as well as the new Safe wallets. If user has a safe with multiple owners, then it is not necessarily a defisaver safe.
