Subject: [PATCH] chore: add .env.example and wire compose.yml to env vars

- .env.example documents all env vars with defaults (postgres creds, DATABASE_URL, TTLs, pool sizes)
- compose.yml reads postgres credentials and app config from .env via env_file
- .gitignore: track .env.example, ignore .env
