fix(ui): remove beta tag from stable services and fix Microsoft Fabric icon (#27638)

- Drop OpenLineage, Wherescape, Cassandra, AlationSink, Cockroach, OpenSearch,
  ThoughtSpot, Ranger, Grafana, and Timescale from BETA_SERVICES — these are
  stable and should no longer show the Beta badge.
- Fix Microsoft Fabric / Microsoft Fabric Pipeline icons: getServiceIcon
  normalizes keys via toLowerCase(), but the map used camelCase keys
  (microsoftFabric, microsoftFabricPipeline), so lookup missed and the tiles
  fell back to the default database icon. Lowercased the keys to match.
