fix: resolve web-read-progress skeleton screen and search-result card disappearing

- Add web_read -> web-read-progress mapping to standaloneUiItems filter in main.tsx
  so web-read-progress cards are no longer mistakenly treated as standalone
- Add web-read-progress to CARD_TYPE_PRIORITY (550) to ensure stable sort order
  and prevent search-result cards (500) from being reordered relative to web-read cards
- Add unique card_id (containing tc.id) to google_search and web_search_deep ui.push
  calls so each search result card can be precisely identified
- Improve uiItem matching in ToolCallStatus to first try exact match via card_id
  containing tc.id, falling back to index-based matching only when necessary;
  this prevents index offset bugs when multiple same-type tools run concurrently
