feat: allow TemplateAdmin to delete prebuilds via auth layer (#18333)
## DescriptionThis PR adds support for deleting prebuilt workspaces via theauthorization layer. It introduces special-case handling to ensure that`prebuilt_workspace` permissions are evaluated when attempting to deletea prebuilt workspace, falling back to the standard `workspace` resourceas needed.Prebuilt workspaces are a subset of workspaces, identified by having`owner_id` set to `PREBUILD_SYSTEM_USER`.This means:* A user with `prebuilt_workspace.delete` permission is allowed to**delete only prebuilt workspaces**.* A user with `workspace.delete` permission can **delete both normal andprebuilt workspaces**.⚠️ This implementation is scoped to **deletion operations only**. Noother operations are currently supported for the `prebuilt_workspace`resource.To delete a workspace, users must have the following permissions:* `workspace.read`: to read the current workspace state* `update`: to modify workspace metadata and related resources duringdeletion (e.g., updating the `deleted` field in the database)* `delete`: to perform the actual deletion of the workspace## Changes* Introduced `authorizeWorkspace()` helper to handle prebuilt workspaceauthorization logic.* Ensured both `prebuilt_workspace` and `workspace` permissions arechecked.* Added comments to clarify the current behavior and limitations.* Moved `SystemUserID` constant from the `prebuilds` package to the`database` package `PrebuildsSystemUserID` to resolve an import cycle(commitf24e4ab).* Update middleware `ExtractOrganizationMember` to include system usermembers.
