perf(eidos): de-duplicate the 10 self-importing components from index.css

Bundle Phase 0. The 10 components that already `import './x.css'` from
their `.svelte` (badge, card, image, password-field, s-text,
s-text-virtual-list, scroll-frames, skeleton, spinner, textarea) were
ALSO @import-ed in index.css — shipping their CSS twice (verified: badge
in both its own chunk and the 851 KB monolith). Removed their @import
lines so they ship only as code-split chunks; added a policy comment so
they're not re-added. Build green (1m21s).
