Fix persistent locations not showing on homepage

The public /api/locations endpoint was only returning locations within 48 hours,
but it should also include persistent locations regardless of their age.

Updated SQL query to: 'WHERE created_at > ? OR persistent = 1'

This ensures that:
- Regular reports show for 48 hours (as intended)
- Persistent reports show indefinitely (as intended)
- Both types appear on the public map and homepage
