fix: clear import progress notification stuck at 100%

The progress notification was detached from the foreground
service on pipeline finish, so a process killed mid-import left an
ongoing notification orphaned in the shade until the next app launch.
Terminal notifications now use their own id, and finishing the
pipeline removes the bound progress notification; swiping the app
from recents cleans it up as well.
