Implement Phase 2 Steps 3-5: Sorting and Search improvements

Step 3 - Trello Smart Sorting:
- Update GetBoards SQL with LEFT JOIN and MAX(c.id) for activity sorting
- Update GetBoardsWithCards to find max card ID per board
- Sort by: 1) Has cards, 2) Newest card activity, 3) Board name
- Trello IDs are chronologically sortable (newer > older)

Step 4 - Todoist Due-First Sorting:
- Update GetTasks ORDER BY with CASE WHEN due_date IS NULL
- Sort by: 1) Incomplete, 2) Has due date, 3) Earliest date, 4) Priority
- Tasks with due dates appear before tasks without due dates

Step 5 - Obsidian Search:
- Add SearchNotes method with LIKE queries on title/content
- Update HandleNotes to check 'q' query param and HX-Target header
- Implement smart partial rendering (obsidian-notes vs notes-tab)
- Add search input with 300ms debounce and HTMX integration
- Real-time search without page reload

Mark Steps 1-5 as complete in PHASE_2_SURGICAL_PLAN.md
All tests passing
