Only migrate locations that have a photo; resequence 1..N + remove stale rows

- supabase_schema.sql: drop the static seed (Male/Female photo sets differ);
rows now come from the migration based on actual uploaded photos
- seed_supabase_locations.py: upload only folders containing a photo, resequence
sort_order 1..N per gender (no gaps), and delete leftover/empty rows so the
app shows only real locations
