Align usage scenarios with v0.4.0 - RGW S3: use the first gateway's keys for a gateway without a user, read FactsOf's two results, import override, and register Restore before the SetConfig error check. - RGW multisite: Run waits for the shared period, not for sync; per-peer shaping exists through ApplyZoneLinkProfile. - RBD: run the rbd CLI in ClientContainer, create EC data pools through ceph.ClusterConfig.WithPools, point to the RBD Mirror page for its helpers, and complete the imports. - RBD mirror: pick the daemon image from each link's destination, state the four-minute bound of WaitReplayReady, and complete the imports. - CephFS: add the import block. - RBD and CephFS mirror: describe the service under test, not Ceph replication, as what the scenarios exercise. - Cluster basics: a MON-only phase cannot keep initial pools, pool flags come from Pool.Status, and mirror links refresh through RefreshMonitorConfig. - Verification: the MON reports OSD_DOWN to the cluster log.

Add usage scenario pages for the current API Home, a sidebar and nine scenario pages (Ceph cluster basics, RBD, RBD mirror, CephFS, CephFS mirror, RGW S3, RGW multisite, fault and condition reproduction, verification and diagnostics). The scenarios come from the examples formerly kept in the package READMEs, rewritten around fixture, hand-off, condition and post-test verification, and every Go snippet compiles against the current API.
