feat(settings): use KindBadge and NIPBadge in relay list accordions

Replace plain text kind names with KindBadge (full variant showing icon,
name, and kind number) and add NIPBadge next to each list description.
This gives power users the protocol context they expect.

Also document KindBadge and NIPBadge as shared components in CLAUDE.md.

+**Shared Badge Components**:
+- **`KindBadge`** (`src/components/KindBadge.tsx`): Displays a Nostr event kind with icon, name, and kind number. Uses `getKindInfo()` from `src/constants/kinds.ts`. Variants: `"default"` (icon + name), `"compact"` (icon only), `"full"` (icon + name + kind number). Supports `clickable` prop to open kind detail window.
+- **`NIPBadge`** (`src/components/NIPBadge.tsx`): Displays a NIP reference with number and optional name. Clickable to open the NIP document in a new window. Shows deprecation state. Props: `nipNumber`, `showName`, `showNIPPrefix`.
+- Use these components whenever displaying kind numbers or NIP references in the UI — they provide consistent styling, tooltips, and navigation.

 **Current Status**: Only NIP-29 (relay-based groups) is supported. Other protocols are planned for future releases.
