fix: code review cleanup

- Added missing API functions: fetchKnowledgeStats, fetchEntryGraph
- Exported StatsDashboard and EntryGraphViewer components
- Replaced 'any' types with proper TypeScript types:
  * AuthUser for @CurrentUser parameters
  * Prisma.KnowledgeEntryWhereInput for where clauses
  * Prisma.KnowledgeEntryUpdateInput for update data
  * Prisma.TransactionClient for transaction parameters
- All TypeScript checks passing
- XSS protection verified in WikiLinkRenderer (escapeHtml function)
- Wiki-link parsing properly handles code blocks and escaping
