Fix db host-port collision: separate DB_HOST_PORT from the internal port

Browse Source 
DB_PORT was doing double duty - the container-internal port baked into
DATABASE_URL (must be 3306) and the host-published port in
docker-compose.yml. Setting it to 3306 for the URL made compose try to
publish host :3306, which collides with another stack's MySQL.

DATABASE_URL now hardcodes database:3306 (always correct inside the
compose network); the host publish uses ${DB_HOST_PORT:-3310}.
