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

[AztecBot]

Summary

• Wait for the setup block to reach the node's proven tip after markAsProven() in the full prover e2e fixture.
• Make full prover node teardown tolerate partial setup so the original setup/test failure is not masked by an undefined stop() call.

CI Failure

Investigated http://ci.aztec-labs.com/1782912672530808. The failing child was FAKE_PROOFS=1 yarn-project/end-to-end/scripts/run_test.sh simple e2e_prover/full, where PXE contract sync queried an anchor block hash that the node had already pruned because the setup proof had not been observed before the proven PXE was started.

Verification

• git diff --check passed.
• ./bootstrap.sh ci could not run in this checkout: Unknown command: ci.
• ./bootstrap.sh ci-fast started, but local-only checks failed before the e2e target (.claude/tests/agents_symlink_test reports workspace symlink issues). The cited dashboard CI skipped claude-tests.
• Direct FAKE_PROOFS=1 yarn-project/end-to-end/scripts/run_test.sh simple e2e_prover/full is blocked in this container by missing yarn-project/node_modules/.bin/jest and no Docker socket.
