feat(tui): unify list interactions across all tabs

[troycdc]

Summary

• Add mouse click/double-click and Enter key navigation to all list tabs (History, Watchlist, Orders, Positions) — previously only Market tab supported mouse interaction
• Fix Market tab empty space at bottom: clicking empty rows no longer selects hidden items or enters detail
• Fix History tab over-scroll: selected item now stays within visible bounds with proper scroll windowing
• Fix History pagination to use correct API cursor-based pagination (end_time/limit) instead of non-existent page_size/page params
• Esc from Market detail returns to the originating tab when navigated via another tab
• Positions tab now uses stable sort (by instrument name) to prevent visual reordering on load
• History time column shows full YYYY-MM-DD HH:MM format

Test plan

• Click and double-click items in Watchlist, History, Orders, Positions tabs
• Verify double-click / Enter navigates to Market detail for the selected instrument
• Press Esc in Market detail after navigating from Watchlist — should return to Watchlist
• Scroll down in History tab with many items — selected row should stay visible
• Navigate pages in History with Right/Left arrows — verify single API request per page
• Verify no navigation beyond last page (Right arrow disabled when no more records)
• Open Positions tab — verify list order is stable across re-renders
