Add hot-reload docker-compose.dev.yml

Dev stack with live reload: Postgres + backend (hypercorn --reload, src mounted)
+ Vite dev server (mounted, proxies /api to the api service). vite proxy target
is now env-configurable (VITE_API_TARGET, defaults localhost:5000 for host dev).
README documents both compose files (dev hot-reload vs prod image).
