StudyDesk v1.0.4

Bug fix release. If you added courses or grades while on 1.0.2 or 1.0.3,
this update recovers all of it.

What was wrong

Since 1.0.2, every write to the cloud was silently failing with a UUID error.
Courses, grades, and study sessions you added were saved locally but never
reached the server — meaning Nexus-Command-Center couldn't see any of it.

What this update does

Fixes the bug going forward: all new records now use the correct ID format
that Supabase expects.

Recovers your existing data: on first launch after updating, the app
automatically finds everything you added locally that never synced, and pushes
it all to the cloud. You'll see a brief "Synced N legacy items" confirmation
when it's done. No action needed from you.

After updating, open Nexus-Command-Center and your courses and grades will
appear there automatically.
