Since the last devlog, I focused on making the dashboard more complete and data-driven. On the backend, I refactored the dashboard service and presenter, expanded the statistics service to return quick stats, daily goal progress, and recent activity, adjusted progress handling, added a migration for renamed character progress columns, cleaned up unused code, and updated the API docs.

On the frontend, I connected the new dashboard data to polished cards for Daily Goal, Recent Activity, Recommended Lessons, and Quick Stats. I also improved module/exercise UI details, cleaned up duplicated or unused components, fixed naming and lint issues, and made small page-level adjustments across the app.

I also expanded the Flashcards feature into a fuller management flow: fetching deck details, editing and deleting decks, editing and deleting cards, refreshing due cards and progress after actions, and resolving warnings around the page state. This makes flashcards feel much closer to a complete study tool rather than just a basic review screen.
