InstallPrerequisites had no alpine branch and threw before Docker
install was ever reached. Enable the community repository (commented
out on some images) and install curl/wget/git/jq with apk.
The Docker install now also pulls docker-cli-compose, which
validateDockerCompose() requires, creates /etc/docker since Alpine's
docker package does not ship it, and enables/starts the OpenRC service.

- Add Arch Linux (pacman) support to server operations: CheckUpdates, InstallDocker, InstallPrerequisites, UpdatePackage
- Implement parsePacmanOutput() to parse 'pacman -Qu' output format
- Add security improvement: package name sanitization to prevent command injection
- Initialize variables in CheckUpdates to prevent undefined variable errors in catch block
- Use proper Arch pacman flags: -Syu for full system upgrade before operations
