refactor(flake)!: use the module system for configurations
' meta.nix
- Move over `auto.confirmations.confirmations`' default value to a separate module (clearing out the associated `TODO`) - Create a module type for the `meta` of each `configurationType`, which streamlines the definition and checking thereof - Pass `meta` instead of just `host` to `predicate`, `mkHost` and `mkDeployNode` - Move the `host != "__template__"` logic inside the default value for `meta`'s `enable` option, leaving it (`enable`) as the main filtering factor in the `configurations`' `predicate`s - Combine `auto.configurations.result{Configurations,DeployNodes}` into `auto.configurations.result.{configurations,deployNodes}`
