feat(mono): Add worker app

[Nudelsuppe42]

This pull request introduces a new standalone worker service in the apps/worker directory, including its configuration, infrastructure, and several utility libraries. The worker is responsible for handling events, background jobs, and scheduled (cron) tasks. See #120 for implementation ideas.

As long as you tested if everything works this looks good to me. I left a few comments about some nitpicky things. Something that might be a good idea to still add is a small docblock above every task explaining what they do (like what you did in the PR description).
