feat: add Filesystems/ObjectStores pages, fix CSI selectors, remove app bar badge (#2)

- Remove AppBarClusterBadge registration (top-bar health bubble)
- Fix CSI pod selectors to match actual pod labels in this cluster
  (was: csi-rbdplugin-provisioner, now: rook-ceph.rbd.csi.ceph.com-ctrlplugin)
- Add FilesystemsPage with detail drawer (Active MDS, data pools, status)
- Add ObjectStoresPage with detail drawer (gateway port, instances, endpoints)
- Register Filesystems and Object Stores as sidebar entries with routes
- Enhance PodsPage OSD table with OSD ID, device class, store type,
  and failure domain columns from pod labels
