UI badge cleanup + /chart-of-accounts route + loop skills (#850)

Bundles three separable concerns:

- style(ui): badge audit + cleanup across 45 files — real-status chips use Badge variants (raw Tailwind colors dropped), non-status count/type/label chips demoted to muted text, clustered badges consolidated; 20 unused imports removed.
- feat(bookkeeping): Kontoplan moved to a dedicated /chart-of-accounts route (nav + command palette wired); /bookkeeping shows the journal list only.
- chore(skills): loop-* automation skills + design-scan workflow under .claude/.

fix(reports): restored the destructive count badge on blocking errors in the periodisk sammanställning (EC Sales List) — a genuine status cue the audit had wrongly flattened; flagged by the PR reviewer and Swedish compliance bot, now clean.

All CI green; compliance bots report no findings.
