feat(l1,l2): ansible rework for deploying ethrex on servers.

[samoht9277]

Motivation

We want a single way to handle Ethrex automated deployments.

This PR aims to close the ansible-dev-deps PR.

Description

This PR adds two Ansible playbooks: one for development and one for standard deploys.

Development deploy

The development playbook is run with

make ethrex-development BRANCH=main

It provisions all required dependencies and leaves the server in a ready-to-use dev state with:

• Single tmux session
• Two panes
• One pane prepped with a Lighthouse command ready to be started
• One pane inside the Ethrex repo, checked out to the selected branch

Standard deploy

The deploy playbook is run with

make ethrex-deploy

It performs a similar setup but runs Ethrex and Lighthouse as systemd services instead of tmux sessions.

In both playbooks, the Lighthouse version can be changed via the lighthouse_version variable in the YAML files. The deploy playbook also allows changing the Ethrex version through ethrex_version

Any changes or suggestions to make the deployment easier are more than welcome.
