CemeteryStep: autocomplete search replaces dropdown, lighter labels

- Select dropdown replaced with MUI Autocomplete (type-to-search
  with search icon) — scalable for large cemetery lists
- Heavy h5 headings replaced with body1 contextual text
- In production, parent can wire this to Google Places API
