frontend: pharmacy inventory, lab add-result & analysis charts

- Pharmacy: the sidebar entry now expands into Pharmacy + a new Inventory page
  (searchable medication stock with derived in-stock/low/out availability,
  backed by /api/inventory). Fix the dispensing-queue "Expiring" badge so it
  only flags courses ending within the next 7 days, not ones already elapsed.
- Lab "Add analysis result": the patient picker no longer lists patients until
  you type and supports arrow-key + Enter selection; the test field offers a
  catalog of common analyses with an Advanced option (custom analysis + ref
  range); submitted results now show immediately in a Recent results feed.
- Analysis: add a Live panel (real-time line chart) and replace the flat trend
  sparklines with bklit-ui area + bar charts (installed from the @bklit shadcn
  registry; chart CSS variables wired into the theme for light and dark).
