test(e2e): wait for proven tip in full prover setup

[AztecBot]

Summary

• Wait for the setup tip to reach the checkpointed chain before warping to the next epoch and marking it proven.
• Wait for that setup tip to become proven before starting the second/full-prover PXE, avoiding PXE sync against a block that can be pruned.
• Make FullProverTest teardown tolerate setup failures before the prover node is created, so the original setup error remains visible.

Investigation

aztec-packages#24388 was removed from the merge queue at 2026-06-30 09:29 UTC after merge-group run 28432921723 failed on temporary SHA 8bbf03bfd38dd76974ff007d7d540c900374bd80.

The failing leg was a1-fast arm64 ci-fast; the wrapper log reported exit 124, and the inner test-engine log showed FAKE_PROOFS=1 yarn-project/end-to-end/scripts/run_test.sh simple single-node/prover/full timing out. The suite log showed setup failing while PXE contract sync queried a block hash that the node had just pruned after the setup epoch warp/proof mark. Teardown then threw on this.proverAztecNode.stop() because setup had not reached prover-node creation.

The first CI run on this PR then failed the same suite earlier with Timeout awaiting block proven >= 6: the prior patch waited on the pre-prune L2 block number, but markAsProven() only marked the latest checkpoint as proven, so an uncheckpointed setup block was still pruned. This update waits for the setup block to become checkpointed before advancing/proving, then waits for that same block to become proven.

Testing

• git diff --check
• ./bootstrap.sh ci did not run locally: this checkout reports Unknown command: ci after Docker/Redis startup checks.
• FAKE_PROOFS=1 yarn-project/end-to-end/scripts/run_test.sh simple single-node/prover/full did not start locally: missing yarn-project/node_modules/.bin/jest in this container.
