fix: path mount which prevented built image from running

the path in docker-compose explicitly mounted /src/lab_mock to /opt/lab_mock
which would have overwritten what would essentially be a bug in the build
step where the files from /src/lab_mock are being copied into /opt/lab_mock/lab_mock
failing the uvicorn command to find the files when the image is built and
pushed to the github repository

we should maintain this image constantly so we can test these simple use cases
this also follows some docker build issues we have had in the past, while
these commands have been documented into tickets
anomaly/lab-python-server#43

we should make them part of the build process and Taskfile
