Add an "Add funds" module to the account creation flow that is integrated with Relay Kit

[gravenp]

Description With https://github.com/Geo-Web-Project/cadastre/issues/400, users will create or sign in to the Cadastre with a "Signer" account. This is intended to be paired with a Safe "Smart Account" for an account abstracted setup even if the user used a legacy EOA to sign-in. If the user's "Signer" account doesn't have a Safe associated with it, we need the user to pre-fund it, create it, and pay for the gas.

Funding can be from a fiat-to-crypto onramp or through an ETH transfer. For the hackathon, we'll just focus on direct ETH funding. Onramp functionality can be listed as "Coming Soon."

*Requirements

• Show a module shown after the "Signer" account creation/first EOA sign-in, requesting that the user fund their target Safe address
  • Don't show this module after sign-in if the Safe already exists. Future designs will also allow the user to select from a list of Safes if they have more than one.
  • Always display the (target) Safe address in the Cadastre header and the profile page rather than the EOA signer
• After the target Safe address has been funded with ETH, prompt the user to create their Safe using the Safe Core SDK
  • Utilize Relay Kit and Gelato's SyncFee to fund the gas required to initialize the Safe from the Safe itself
• Make this "Add Funds" UI module available from the user dashboard and transaction windows
  • Show the Add Funds module when the user clicks on their account address in the header if they haven't yet initialized their Safe instead of the full profile modal
  • Update the "Insufficient ETHx" warning message/logic to be shown if the user hasn't initialized their Safe and/or doesn't have enough ETH+ETHx balance to complete the transaction:
  • "Insufficient Funds - Click Add Funds above and send ETH to your account to complete your transaction"
  • After the Safe is created/funded the first time, only the functions/information pertaining to sending funds to the Safe are needed.

Closed with changes merged into the Safe branch. Will open a ticket for merging any changes to develop & production when appropriate.
