Introduce prospects API, remove products, bump version

Refactor API surface: remove the app/api/products package and its CSV/data files and replace it with a new app/api/prospects package (prospects.py and seed/data CSVs). Rename/move seed router (products/seed.py -> prospects/seed.py) and relocate db module from app/api/db.py to app/utils/db.py. Bump package version to 1.1.2 and update api package docstring; update main, root and routes to accommodate the new structure. Note: .DS_Store files were added (OS artifacts).
