refactor(build): unify Dockerfiles and runner script

Replaced separate Fedora and Ubuntu Dockerfiles with a single parameterized
Dockerfile using BASE_IMAGE. Removed distro-specific runner scripts and added
a unified run.sh supporting both Fedora and Ubuntu via a -d flag. Updated
README to reflect new usage. Improved install-node.sh to handle both distros
and moved timezone setup into the script for consistency.
