Fix gateway initialization by properly funding escrow during setup

[neithanmo]

The gateway service was failing to initialize properly because the escrow contract wasn't being funded correctly. This was causing the gateway's health check to fail with connection reset errors, even though the container was running.

• Added proper error handling and logging for the escrow funding process
• Integrated the escrow funding into the main setup script at the correct point (after gateway deployment, before health check)

This also has the benefit of using local-network configuration directly in our funding instead of defining constants.

Note

Previous funding script remains in place, maybe useful out of the local-testnet setup
