Filter panel UX refinements: headings, layout, location chip, padding

- DialogShell: bump px from 3 to 5 (20px) for more breathing room
- FilterPanel: "Done" → "Apply", move "Clear all" to footer as "Reset filters"
- ProvidersStep filters:
  - Section headings: labelLg + fontWeight 600 for visual hierarchy
  - Funeral type chips: horizontal scroll instead of wrap
  - Location section: chip showing current search + editable input
  - Price inputs: compact fontSize 0.875rem + tighter padding
  - Service tradition: 'None' added as first option
  - Active count includes location search
  - Reset clears search query too
