Update docker-compose and .env.example

Error:

Database URL: 
Environment variables loaded from .env
Prisma schema loaded from prisma/postgresql-schema.prisma
Datasource "db": PostgreSQL database "evolution", schema "public" at "localhost:5432"
Error: P1001: Can't reach database server at localhost:5432

Fix:

Update `docker-compose.yaml` and `.env.example` files to configure PostgreSQL service and connection URI.

* **docker-compose.yaml**
  - Add `listen_addresses=*` command to the `postgres` service.
  - Add environment variables: `POSTGRES_USER=user`, `POSTGRES_PASSWORD=pass`, `POSTGRES_DB=evolution`, `POSTGRES_HOST_AUTH_METHOD=trust`.

* **.env.example**
  - Update `DATABASE_CONNECTION_URI` to `postgresql://user:pass@postgres:5432/evolution?schema=public`.
