Subject: [PATCH 1/3] chore(ci): use apache archive for cassandra download

dlcdn is only for the latest versions, we were using 5.0.6 which was
removed when 5.0.7 was released. In this change we use archive.apache.org
which has all the versions and we increment to 5.0.7 while we're at it.

Subject: [PATCH 3/3] fix(lotus): disable unreleased network upgrade
 (UpgradeXxHeight) in devnet

Lotus 2k builds schedule UpgradeXxHeight at epoch 200, triggering an
expensive state migration that causes transient ErrExpensiveFork on
eth_call/estimateGas. Set LOTUS_XX_HEIGHT=-1 on the daemon container
to prevent this.
