fix(mls): update kalium for recipient warning [WPB-8645]

[MohamadJaara]

https://wearezeta.atlassian.net/browse/WPB-8645

Summary

• Update the Kalium submodule to include the MLS unreachable-recipient warning fix.
• Enable an Android CI build for QA validation of testcase C1312852.

Dependency

• Kalium implementation: fix(mls): show unreachable recipient warning kalium#4384

Root cause

Kalium classified MLS failed_to_send recipients as a temporary delivery failure. Android therefore did not display the existing warning that an unreachable federated participant would not receive the message.

Impact

The message remains sent to available participants. When the backend returns an unreachable user in failed_to_send, the sender sees that the participant won't get the message.

QA

Please validate testcase C1312852 with an MLS conversation spanning multiple federated backends and one disabled federator.

Validation

• Focused Kalium Android host tests pass for the response mapper, sender, and network decoder.
• Kalium static analysis passes.
