Clarify initial setup instructions in README

Prior to this change, the instructions for starting the environment and seeding the database were unclear.

This change provides detailed steps for initializing the database and starting the environment in separate terminals, ensuring users understand the process better.

Also fix some services not shutting down when using the stop script.

 ## Getting started
 
 ### The first time
-If you are doing this for the first time, first start the environment and then seed it:
+On first run, the `engine` service requires the database to be initialised before it can become healthy.
+Start the environment in one terminal, then run the init script in a second terminal.
 
-1. Start the environment:
+**Terminal 1** — start the environment (this will block while waiting for all services to become healthy):
 ```
-./start-dev-env.sh
+./start-dev-env.sh engine:/path/to/OpenConext-engineblock
 ```
 
-2. Once all containers are up, seed the environment:
+**Terminal 2** — once you see mariadb and engine starting in terminal 1, seed the environment (the script waits internally until they are ready before proceeding):
 ```
 ./scripts/init.sh
 ```
 
+After init completes, terminal 1 will finish and the environment is ready.

 ### After initialisation
-To start the environment again after the initial setup:
+To start the environment again after the initial setup, a single terminal is sufficient — engine will become healthy on its own because the database is already initialised:
