feat(astrolabe): enhance unified search and add webhook management

Improve unified search results with chunk/page metadata and add
webhook management capabilities to McpServerClient.

Changes:
- SemanticSearchProvider improvements:
  - Display chunk position (e.g., "Chunk 2/5")
  - Display page numbers for PDFs (e.g., "Page 3/10")
  - Fix file links to open in Files app correctly
  - Fix deck card links to use proper URL format
  - Show metadata in subline before excerpt
  - Use proper icons and thumbnails for each doc type
- McpServerClient webhook methods:
  - listWebhooks() - Get all registered webhooks
  - createWebhook() - Register new webhook
  - deleteWebhook() - Remove webhook registration
  - enableWebhook() / disableWebhook() - Toggle webhook status
  - getWebhookLogs() - Retrieve delivery logs

Benefits:
- Better search result context with chunk and page info
- Clickable links that open correct resources
- Full webhook lifecycle management via API
