* feat: support general users view and cancel own tasks
Add a creator attribute to the upload, copy and offline download
tasks, so that a GENERAL task creator can view and cancel them.
BREAKING CHANGE:
1. A new internal package `task` including the struct `TaskWithCreator`
which embeds `tache.Base` is created, and the past dependence on
`tache.Task` will all be transferred to dependence on this package.
2. The API `/admin/task` can now also be accessed via `/task`, and the
old endpoint is retained to ensure compatibility with legacy
automation scripts.
