test(cypher): align the explicit-LIMIT case with the engine projection budget

b798350 capped an explicit LIMIT at max_rows so an oversized limit cannot
bypass the engine projection budget, and added cypher_return_distinct_counts_
distinct_rows_against_cap_issue1364 to lock that in. cypher_apply_limit still
carried the older TestApplyLimitRespectsExplicit reading (LIMIT 30 with
max_rows=10 returns 30 rows), so the two contracts collided on
release-tooling and the Jenkins shard failed on it.

The clamp is deliberate: it ships with its own regression test and matches
the engine-budget contract, so update cypher_apply_limit to expect the capped
10 rows and truncated:true instead of reverting the guard.
