Add store settings page with location management

Company table gains address and logo_file_id columns. New store
settings API: GET/PATCH /store for company info, full CRUD for
/locations. Settings page shows store name, phone, email, address,
timezone with inline edit. Location cards with add/edit/delete.
Settings link in admin sidebar. Fixes leftover company_id on
location table and seed files.
