fix: Change library ordering to oldest-first

Change library ordering in dropdown from DESC to ASC to display
libraries in creation order (oldest first).

Database changes in internal/database/queries/queries.sql:
- Modify GetUserLibraries query ORDER BY clause
  - Change from ORDER BY l.created_at DESC to ASC
  - Displays oldest libraries first in dropdown

This provides a more intuitive ordering where users see their
first-created libraries at the top of the list.
