Fix dagger call hanging in mise tasks on interactive terminals

Browse source 
Mise runs task scripts in a child process group that is not the
terminal's foreground group. When dagger detects a TTY it tries to
render its TUI, triggering SIGTTOU which stops the process. Adding
--progress=plain to all dagger call sites avoids terminal ioctls.

Fix Dagger pipelines hanging when called from mise tasks in interactive terminals. Added `--progress=plain` to all `dagger call` invocations to prevent SIGTTOU from stopping the process when mise's child process group is not the terminal foreground group.
