Adopt Portainer/Beszel-style fleet controls: prominent search, status
facet chips with counts, active filter chips, result count, and
primary-row sort/select. Keep advanced filters collapsed for secondary
facets. Tests and production dist rebuild for gateway 8788.
Drop the redundant advanced table so fleet stays resource-first cards.
Keep multi-select batch service/system restart via prepare→execute, card
restarts, overview system ops, and progressive fleet loading.
