Fix FinOps collector scheduling, server switch, and utilization bugs

- Add database_size_stats_collector and server_properties_collector to
  install seed data so fresh installs get FinOps collectors (fixes #531)
- Load all per-server FinOps sub-tabs on server switch (fixes #530)
- Clear stale utilization grids when switching servers (fixes #532)
- Fix NoUtilizationMessage layout (RowSpan, alignment, margin)
- Change CROSS JOIN to LEFT JOIN for server_info in Lite utilization
  query so data shows even without v_server_properties (fixes #533)
- Remove stale debug JSON files
