fix(AttackOrchestrator): increase gas forwarded to 5300 for SSTORE

The attack() call was forwarding only 3650 gas, which is insufficient
for SSTORE operations on cold storage slots. SSTORE requires:
- 2100 gas for cold slot access
- 2900 gas for zero-to-nonzero write
- Plus dispatch overhead (~200 gas)

Updated to forward 5300 gas to ensure SSTORE succeeds.
