[simplex]: shut down filler on delegation failure + raise set-code gas limit

[royvardhan]

Addresses two issues raised by David on the filler's EIP-7702 delegation:

• Fail fast. The filler now shuts down when delegation fails on all solver-selection chains. If only some chains fail, it logs a warning and continues on the chains that succeeded.
• Gas limit error. Raised the flat set-code (0x04) gas limit from 350K → 650K, and fixed the Turnkey signer path which never applied the limit (it let viem estimate ~94k, which L2s reject).

does this shutdown when any chain delegation fails or when all fails?

When any fail, so that on a restart, it skips the delegated ones and directly try failed ones.

Should be when all fails

Then if it continues to run, it will not be able to fill an order for the destination where it failed to delegate?

That's fine
