Archive / hide projects without deleting them

What problem will this feature address?

Over time, completed or inactive projects accumulate in the dashboard. There is currently no way to hide or archive them — the only option is deletion, which removes all configuration and history.

This clutters the project list and makes it harder to focus on active work.

Describe the solution you would like

Add an Archive action for projects that:

1. Hides the project from the default dashboard view
2. Optionally stops all running services in the project
3. Preserves all configuration, environment variables, domains, and deployment history
4. Allows restoring (unarchiving) at any time
5. Adds an "Archived" filter/tab to view archived projects when needed

Additional context

This is a common pattern in project management tools (GitHub repos, Linear, Notion databases) and would be a natural addition to the Dokploy workflow. Especially useful for freelancers and agencies who cycle through many client projects.

No files, tests, or entry points are named. Start by tracing how projects appear in the dashboard and how project services are started or stopped. Define the archive state, dashboard filtering, restoration behavior, and preservation of configuration and deployment history before implementation.
