feat(dashboard): show course progress in student sidebar (#761)

* feat(dashboard): show course progress in student sidebar

Adds a progress ring with completed-lesson count to the course sidebar
header, per-section completion percentages in the content tree, and a
"Your progress" footer card with an overall progress bar plus a
lessons/exercises breakdown. All indicators are student-only and derive
from the existing per-item isComplete flags, so they update live when a
lesson is marked complete.

* feat(dashboard): show course progress ring in header on mobile

Extracts the sidebar footer progress card into a reusable
course-progress-card component and adds a course-progress-popover
(progress ring trigger, mirroring the org nav setup ring) to the course
header beside the Assistant button. Shown to students on mobile only,
where the sidebar footer card is hidden; tapping the ring opens a
popover with the linear progress bar and lessons/exercises breakdown.

* fix(dashboard): align progress ring subtitle with ring scope

The header ring percent covers lessons and exercises while the subtitle
only counted lessons, which contradicted each other on courses with
exercises. The subtitle now uses the same all-content counts. Also
drops a duplicate useSidebar import in favor of the namespace export.
