- Created initiated_filter_dropdown() and last_seen_filter_dropdown() components
- Uses rx.select.root pattern with static options for Reflex compatibility
- Updated filter_section() to use new dropdown components
- Removed old date_range_picker() function (replaced by new dropdowns)
- Data freshness indicator already working in top_bar via load_pathway_data()
- Verified: py_compile PASS, imports PASS, reflex compile PASS (11.1s)
Updated the icicle_figure computed property in AppState to use the full
10-field customdata structure matching visualization/plotly_generator.py:
- value (patient count)
- colour (proportion of parent)
- cost (total cost)
- costpp (cost per patient)
- first_seen (first intervention date)
- last_seen (last intervention date)
- first_seen_parent (earliest date in parent)
- last_seen_parent (latest date in parent)
- average_spacing (dosing information)
- cost_pp_pa (cost per patient per annum)
Updated texttemplate and hovertemplate to display treatment statistics
including duration, dosing, and full cost breakdown.
- Add dropdown state for date filters (selected_initiated, selected_last_seen)
- Add date_filter_id computed property combining the two selections
- Add load_pathway_data() method to query pathway_nodes table
- Add recalculate_parent_totals() for filtered hierarchies
- Update all filter handlers to call load_pathway_data()
- Update KPI calculations from root node data
