feat(web): Current/All space filter + redesigned chat history sheet

[MaheshtheDev]

Add a Current/All scope toggle (default Current) to Nova chat history; All fetches threads across every space via the new scope=all API, with each row showing its space.

Redesign the sheet to fit the design system: cap width at 380px (was ~92vw), add search, date-grouped rows (Today/Yesterday/Previous 7/30 days/Older), hover-reveal delete, header space chip, solid primary New Conversation button.

Overview: Adds a Current/All space scope toggle to the chat history sheet with search functionality and date-grouped thread display.

Issues found: None — this looks good to ship.

The implementation is solid:

• URL construction using URLSearchParams is safe and handles the scope parameter correctly
• Date grouping logic properly handles timezone-relative bucketing (Today/Yesterday/etc.)
• Search filtering correctly handles null/undefined titles with (t.title || "")
• State cleanup on sheet close properly resets confirmingDeleteId and historySearch
• The useMemo for threadGroups has correct dependencies
• Keyboard accessibility is properly implemented with role="button", tabIndex={0}, and Enter/Space handling
• The useEffect correctly re-fetches when historyScope changes
• No XSS vulnerabilities — React's built-in escaping handles user content

Score: 10/10
