Swap Preview Solr for VFBquery cache (v0.11.5)

- Drops Preview Solr (query-preview.virtualflybrain.org / 1s322)
  from solr_services. The cache in front of vfbquery is the more
  operationally relevant endpoint to watch.
- Adds VFBquery cache (vfbquerycache.virtualflybrain.org) to
  cache_services. LB-only for now (no rancher: block); a stub
  rancher: snippet is commented out and ready to be uncommented
  once the rancher service id is known.

NOTE: as of this commit the public hostname
vfbquerycache.virtualflybrain.org doesn't have an LB rule in
RancherServices/vfb-services-live and falls through to the Hugo
catch-all on every path. The card will show red until either
the LB rule is added or the rancher: block is filled in.

 - A container failing writes is marked not-ok (so it counts against uptime and surfaces in the cluster-degraded table) and the Solr card shows a `writes failing ⚠` badge. New fields `u_server_errors`, `write_ok`, `write_detail` on `/api/solr`.
 - `solr_history.u_server_errors` column, added to existing databases via the standard `_migrate()` ADD COLUMN path.

+### Changed
+
+- **Removed `Preview Solr (query-preview.virtualflybrain.org)`** from `solr_services` — `query-cache-server` (1s322) is operationally less interesting to track than the cache in front of it.
+- **Added `VFBquery cache (vfbquerycache.virtualflybrain.org)`** to `cache_services`. Currently LB-only (no rancher: block); the public hostname doesn't have a rule in `RancherServices/vfb-services-live/rancher-compose.yml` yet and falls through to the Hugo catch-all, so the card will show red until either the LB rule lands or we wire the rancher: block with the right service id. Stub commented out in the YAML — ready to be uncommented.
