Introduce an L1 resolution threshold on ETH balance on L1

[fredo]

The agent has a shared accounting for its balance on L1 between the LPing task and the L1 resolution task. This means that when there is a lot of volume, the ETH could get staked into the RM and nothing is left for a critical L1 resolution operation.

solution:
Introduce a (configurable) threshold which makes the agent stopping filling, when below this threshold.

Sub problem: We need to think about claiming and challenging.

We need to also think about how to check that the chain id is the same as the web3_l1 chain id.
