[ST] Shutdown ETH transfers to Mode

[MinistroDolar]

Describe the bug

At this moment we've 2 major issues regarding ETH transfers to Mode.

1. Liquidity in the pool is too low (less than 2 eth)
2. Bridge UI is giving wrong estimated outputs when simulating a transfer

This is leading to users initiating transactions based on wrong information, as we see in the tickets: #6317 and #6319

So, we should shut down this route as soon as possible to avoid more users getting stuck. Most of them will be forced to receive nextWETH and bridge back to another chain, which is a terrible experience and dependent on the team providing the instructions.

Additional context
#6317
#6319
