feat(core-ui): Claude Code icon in harness dropdown, drop credentials badge

- ConfigPicker harness dropdown rows now render the Claude Code mark
  as a leading icon (PickerRow gained an optional `icon` prop).
- Removed the Anthropic credentials status pill from the composer
  chrome per request. Deleted the AnthropicStatusBadge component and
  its now-dead plumbing: the anthropicState/anthropicStatus props
  threaded ConfigPicker ← SessionView ← AppShell, and AppShell's
  useAnthropicStatus consumption. The hook + anthropic-status lib stay
  (still used by the harness settings page).
