* Updated the base image in `Dockerfile.dev` from `node:18-alpine` to `node:lts-alpine` to use more or less the same as for production docker build (where the client is build lts and server is 18... so yeah not really...)
* Removed the `USER node` directive, to prevent permission issues as we hook the whole folder into the container.
* Modified the `docker-compose-dev.yml` file to enhance the database healthcheck. The new healthcheck ensures not only postgres is ready but also the database is ready by running a sample query (`SELECT 1`) and adjusts the interval, retries, and start period for better reliability.
* Added a `nodemon.json` configuration file to watch only relevant files (node_modules would be ignored but not files like the python venv) and avoid rapid successive restarts with the delay.
