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.
Collapse the redundant left workspace nav (overview is already the home
surface) and move Settings into the top bar. Hide placeholder `dev`
version badges. Restyle fleet cards with softer elevation, status
summary chips, hover sheen, and reduced-motion-safe entrance motion.
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.
