Address PR #1211 code review feedback

1. ServerCard: import ConnectionStatus and ServerType from core instead
   of inline union types
2. ResourcePreviewPanel: move ContentBlock import to top of file
3. ContentViewer: remove dead annotation mimeType check in isJsonText
4. ProgressDisplay: use Pick to exclude progressToken from params type;
   remove fake tokens from callers and stories
5. AnnotationBadge: restore human-readable priority labels (high/medium/low)
   and remove unused --inspector-annotation-* CSS vars from App.css
6. MessageBubble: add fallback rendering for resource, resource_link,
   tool_use, and tool_result content block types
7. TaskControls: import TaskStatus directly from SDK instead of via TaskCard
