Create FHE instance fails with CALL_EXCEPTION on FHEVM Host chain (0.3.0-5 and 0.2.0)

[0xethll]

• Summary

The SDK call to the KMS Verifier contract on the FHEVM Host chain fails with CALL_EXCEPTION: missing revert data.
This happens with "@zama-fhe/relayer-sdk": "0.3.0-5" and also with "0.2.0".

• Steps to Reproduce

1. Install @zama-fhe/relayer-sdk@0.3.0-5 (or downgrade to 0.2.0)
2. Initialize following the “Create an FHE instance” step
3. During initialization, the call to the KMS Verifier contract fails

• Actual Behavior (logs)

SDK 0.3.0-5:
Error: missing revert data (action="call", data=null, reason=null, transaction={ "data": "0x7eaac8f2", "to": "0xbE0E383937d564D7FF0BC3b46c51f0bF8d5C311A" }, invocation=null, revert=null, code=CALL_EXCEPTION, version=6.15.0)

SDK 0.2.0:
Error: missing revert data (action="call", data=null, reason=null, transaction={ "data": "0x7eaac8f2", "to": "0x1364cBBf2cDF5032C47d8226a6f6FBD2AFCDacAC" }, invocation=null, revert=null, code=CALL_EXCEPTION, version=6.15.0)

• Additional Context

In a recent commit, the FHEVM Host chain KMS_VERIFIER_CONTRACT_ADDRESS changed from
0x1364cBBf2cDF5032C47d8226a6f6FBD2AFCDacAC to 0xbE0E383937d564D7FF0BC3b46c51f0bF8d5C311A (see screenshot).
Both addresses currently fail during initialization with “missing revert data”. The call selector is 0x7eaac8f2.

@poppyseedDev Would you have a chance to review? I'm packaging a generic SDK, but it's not working properly right now.
