* feat: Add Medication Refill feature with UI improvements

- Add refill functionality to medications (add packs/loose pills)
- Add refill API endpoint with history tracking
- Add refill section in edit forms (desktop & mobile)
- Add refill modal in medication detail view
- Add refill history display with expand/collapse
- Add schedule lightbox for clicking medication images
- Improve button styling with primary/info/success classes
- Move '+ New entry' button to medication list header
- Lightbox size: 50% desktop, 90% mobile
- Update selectedMed sync after stock changes
- Migrate from schema-sql.ts to Drizzle Kit migrations

* fix: Improve mobile tooltips and refill modal layout
