build: Build and deploy testnet

[bgins]

Review Type Requested (choose one):

• Glance - superficial check (from domain experts)
• Logic - thorough check (from everybody doing review)

Summary

This pull request implements the following changes:

• Remove Cloudflare token and Doppler environment from solver and job creator Dockerfiles
• Add testnet_deploy_contracts action
• Add testnet_deploy_services action to build and deploy solver and job-creator to Testnet
• Add testnet_restart_solver and testnet_restart_job_creator actions to restarts services individually
• Update Devnet documentation to use Ubuntu instead of Amazon Linux

All GitHub actions are run on-demand for the moment.

Note that testnet_deploy_contracts depends on the #122 where the arbitrumSepolia network is defined. We could wait on this one if we prefer to hold off until the other PR is merged.

Task/Issue reference

Implements #124

How to test this code?

Local builds for the Docker images should succeed and work with the local stack.

The GH actions can only be run on-demand once this PR reaches main, but here are the last runs while working on them:

• testnet_deploy_services: https://github.com/Lilypad-Tech/lilypad/actions/runs/9310164136
• testnet_restart_solver: https://github.com/Lilypad-Tech/lilypad/actions/runs/9312184243
• testnet_restart_job_creator: https://github.com/Lilypad-Tech/lilypad/actions/runs/9312184244

testnet_deploy_contracts has not been tested, but is quite similar to the Devnet contract deploy action:

We need to validate this works locally, to confirm we get the same contract addresses every time.
