refactor: import the sql file when the service starts

-On a fresh Docker volume, Compose creates the MySQL database `agileboot_pure`.
-Import the SQL files under `backend/sql/` before starting the backend.
+The compose configuration mounts `backend/sql/agileboot.sql` into the MySQL
+container as `/docker-entrypoint-initdb.d/01-agileboot.sql`.
+The official MySQL image only runs files in `/docker-entrypoint-initdb.d` when
+the database directory is empty, during the first initialization of the
+`mysql_data` volume.
+
+If MySQL has already been started before, the `mysql_data` volume already
+contains data and `docker compose up -d` will not import the SQL again. To
+reinitialize the local database, remove the volumes first:
+
+```bash
+cd backend
+docker compose down -v
+docker compose up -d
+```
+
+Warning: `docker compose down -v` deletes the local MySQL and Redis volumes,
+including existing database data and Redis data.
+
+If you do not want to delete the volumes, import the SQL manually:
+
+```bash
+cd backend
+docker exec -i mysql-server mysql -uroot -proot123 agileboot_pure < sql/agileboot.sql
+```
