Offline support MVP

[NVivero]

Feature Overview
LME is building support for offline/air-gapped deployments. This feature enables organizations operating in isolated environments, with no direct access to the internet, to install and operate LME.

Problem Statement
Many organizations operate in air-gapped networks where internet connectivity is restricted or entirely disabled. Currently, LME's installation process depends on downloading packages, containers, and updates from online sources. This online dependency makes LME inaccessible to users in these high-security or disconnected environments, limiting its adoption and reducing visibility where it’s often needed most.

Solution Statement
Introduce an offline deployment capability that allows users to install and configure LME in air-gapped environments. A new --offline flag in the Ansible playbook enables the installation process to run entirely using pre-loaded packages and containers embedded within the deployment image. This MVP development effort is focused on providing users with a downloadable artifact (tar.gz) that contains everything needed for an offline install.
