Docker-compose: do not access ports <443

[toger5]

This does not allow podman (also docker) to start the containers without altering linux default security measurements.

The playwright tests also run with those the alternative ports: 4443, 8080, 8081

this PR is missing the required changes for dev-backend-docker-compose.yml to work properly as removing port 443 requires a bunch of config files to be adapted https://hostname becomes then https://hostname:port

As a workaround for podman

You can modify the net.ipv4.ip_unprivileged_port_start sysctl to change the lowest port. For example sysctl net.ipv4.ip_unprivileged_port_start=443 allows rootless Podman containers to bind to ports >= 443.

I updated the PR to still include the :Z flag for the file copy and allow to set the min port to 443. (instead of 80)

[fkwp]

The .well-known URI can only be reached via HTTPS on the default 443 port. Due to this limitation the highest possible port is bound to 443

[toger5]

I actually did run into issues using the dev env in firefox (not playwright) not sure if that is an issue. I think some routing is done through port 80.
So eventually we need to update the nginx conf or also allow port 80?

Lets merge this as is. In case there is another issue with the local lk server we can fix this in another PR.
