Subject: [PATCH] test(integration): add P10.2 node_master_key rotation
 acceptance tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements plan §9 zero-downtime rotation flow acceptance tests:
- 4-step rotation flow: create new key → update secret → rolling restart → delete old key
- Mid-rotation pod restart: old and new keys both valid concurrently
- Dry-run mode verification
- Multiple nodes rotation with rollback handling

Tests use testcontainers for real Meilisearch instances to verify the
CLI and runbook implementations work correctly.

Closes: miroir-46p.2
