refactor(dashboard): fix dark theme + two-column layout on agent-skills, standardize page widths

- agent-skills: replace all inline style={{ color: "var(--color-xxx, #fallback)" }} with
  Tailwind semantic classes (text-text-main, text-text-muted, bg-bg-subtle, border-border,
  text-primary, bg-primary/10, bg-emerald-500/10, bg-amber-500/10) — fixes dark mode
- agent-skills: full-width "How to use" card + two-column grid (API Skills | CLI Skills)
  on lg+ screens; remove internal p-6 and max-w-3xl (layout already provides padding/max-w)
- audit, webhooks: remove redundant p-6 + mx-auto max-w-7xl (DashboardLayout already wraps
  content in max-w-7xl with p-4 sm:p-6 lg:p-10)
- memory: remove extra p-6
- agents: remove p-6 + max-w-5xl mx-auto
- cloud-agents: remove p-6 + max-w-6xl mx-auto
- changelog: remove max-w-5xl mx-auto w-full
- health: remove outer p-6 + max-w-6xl mx-auto; strip redundant p-6 from loading/error states
- translator: remove p-4 sm:p-8 (layout provides padding)
- context/caveman, context/rtk, context/combos: remove mx-auto max-w-6xl
