fix(sidebar): stabilize feed order and reduce jitter

- Sort feeds alphabetically in Sidebar to prevent random reordering.

- Increase update debounce to 1s (3s during sync) to smooth out jumping numbers.

- fix(bookmarks): Use robust in-memory sort for 'Saved' view to fix missing articles issue caused by compound index failure.
