Andrew Charlwood 7aa49b0d6b refactor: restructure sidebar with chart views, remove placeholder items (Task 7.3)
- Remove non-functional sidebar items: Cost Analysis, Export Data
- Remove filter trigger items: Drug/Trust/Directory Selection, Indications
- Add Chart Views section: Icicle Chart (active), Sankey Diagram (disabled), Timeline (disabled)
- Remove tab row from chart_card.py (chart view selection now in sidebar)
- Remove open_drawer callback (sidebar no longer has filter triggers)
- Add .sidebar__item--disabled CSS class
